Symptoms Of a Bad Blower Motor Resistor
by
in AutomobileA blower motor resistor is an electrical component that can prevent current from entering the blower fan motor. By increasing the resistance, the fan won’t spin as quickly, which reduces the amount of hot or cold air that is circulated in the cabin. So how do you tell when this component goes bad? Symptoms Of…
Understanding Servo Motor
A servo motor is a type of motor that has a high degree of precision in rotation. Servo motors often have a control circuit that provides feedback on the current position of the motor shaft; this feedback allows them to rotate with great precision. A servo motor is used when you wish to spin an…
Understanding resistors in AC and DC circuit
Ohm’s law (V = IR) still applies in a circuit with a resistor and an AC power source. The passage of electric charge in only one direction is known as direct current (DC). It is the constant-voltage circuit’s steady state. The majority of well-known applications, on the other hand, rely on a time-varying voltage source.…
Understanding combination resistors in series and parallel
In a circuit, resistors can be connected in series or parallel. The total resistance of a group of resistors is determined by their values as well as the way they are connected. A resistor is a component that restricts the flow of charge in a circuit. Most circuits use multiple resistors. The term “resistance” refers…
Understanding parallel resistors
When both terminals of a resistor are connected to each terminal of the other resistor or resistors, they are said to be connected in parallel. Unlike series resistor circuits, because there are several channels for current in a parallel resistor network, the circuit current can take multiple paths. Current dividers are then applied to parallel…
Understanding series resistors
In an electrical circuit, engineers connect the components inside either series or parallel to make a range of useful circuits. With this, we can calculate the voltage, current, and resistance in the circuits. These resistors are said to be connected head-to-tail when in series, and the equivalent overall resistance is the sum of the individual…
Different types of resistors
There are various types of resistors out there, but fixed resistors have resistances that only change slightly with temperature, time, or operating voltage. the variable resistors are used to adjust circuit elements such as volume control or a lamp dimmer. Also, it is used as a sensing device for heat, light, humidity, force, chemical activity,…
Understanding Light dependent resistor LDR
Light-dependent resistors also known as LDRs, or photoresistors are electronic components used to detect light and change the operation of a circuit dependent upon the light levels. Light-dependent resistors are often used in electronic circuit design, where the presence or level of light needs to be detected. This resistor has a variety of names from…
Understanding metal oxide film resistors
Metal oxide film resistors are one of the most widely used resistors because they are superior in performance to the carbon composition and carbon film resistors. As the name indicated, metal oxide film resistors axially loaded resistors are made from a thin film of metal oxide that has been deposited into a ceramic rod. They…
Understanding resistor color codes
Often time, resistor values are indicated with color codes, that is, all leaded resistors with a power rating of up to one watt are marked with color bands. The color coding is described in the international standard IEC 60062. This standard explains the marking codes for resistors and capacitors. Numerical codes are also used in…
Understanding Thermistor
The use of thermistors is of many purposes, as they as straightforward device that changes their resistance to temperature. A thermistor is a term derived from the word “Thermal resistor”, it is a thermally sensitive resistor, giving a change in resistance for a temperature change. Thermistors are used in many ways, enabling the temperature of…
Understanding wire wound resistor
Wire wound is a type of resistor designed to be used in high power resistor applications or some other use where low noise and power dissipation are required. It is one of the oldest forms of resistor that appear as a wire that is wound around a former of nonconductive material. Normally, the resistive wire…
Understanding varistor
Being a form of a resistor, varistors are two-terminal semiconductor components that protect the electrical and electronic devices from overvoltage transients. In fact, the word is derived from the term variable and resistor, which is why it is also known as Voltage-dependent resistor VDR. Varistors are nonlinear varying resistance, dependent on the voltage applied. Their…
Understanding SMD Resistors (Surface Mount Resistors)
The SMD resistors used surface mount technology SMT to offer considerable advantages in terms of space-saving and automated manufacture of the printed circuit boards. Surface-mount resistors are used in large quantities, most professionals and industrial electronics now employ this technology. These types of resistors are designed to be surface mounted and they are typically much…
Understanding metal film resistor
Metal film resistors are one of the most widely used types as they are superior to carbon film resistors in performance. They have a thin metal layer as a resistive element on a non-conducting body and are one of the most common types of axial resistors. Carbon film and thick and thin-film resistors are also…
Understanding carbon firm resistor
Over the years, the carbon film resistors have taken over from the carbon composition resistor, due to their portability and ability to provide a much better performance level. These types of resistors can be compared with metal film and metal oxide film, and they are widely used in electronics. This is because they provide better…
Understanding carbon composition resistor
Carbon composition resistors are one of the oldest types that have been around since the 1960s. there are many modern resistors that offer better performance although they are still used in some specialized applications. Also, the carbon composition resistors are of high cost and have low stability. They are known as carbon resistors or carbon…
Understanding resistors
Resistors are great electrical components used to reduce current flow, adjust signal levels, divide voltages, bias active elements, and other uses. It is a passive two-terminal electrical component that implements electrical resistance as a circuit element. High-power resistors are designed to dissipate many watts of electrical power as heat, may be used as part of…
