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…
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 ultracapacitors
Ultracapacitors are also known as a supercapacitor or an electrochemical capacitor. Ultracapacitors are electrical energy storage devices that store electrical charges in large amounts. It does not lose its energy just like the ideal capacitors. Well, the simplest form of capacitor has two parallel conducting metal plates that are separated by an insulating material like…
