## How to calculate Equivalent Resistance?

Equivalent Resistance of a circuit is obtained by calculating parallel and series elements in a circuit. A circuit may contain many series and parallel connected elements. In this topic on How to calculate Equivalent Resistance, we have to simplify the circuit elements. To find the value of a resistor, a multimeter of Resistor Color Coding …

## Kirchoff’s Current Law and Kirchoff’s Voltage Law | KVL and KCL

In this post, a clear explanation on KVL and KCL has been provided. Kirchoff’s Current Law and Kirchoff’s Voltage Law can be applied only a closed path or loop. Kvl & Kcl Also, read: Equivalent Resistance | Calculation Ohm’s Law | example Kirchoff’s Current Law : In the above circuit, the I1, I2, I3, I4, and …

## Ohms Law def | Ohms Law with an example problem

Ohms law def and Ohms Law with an example is shown here. In other words, it can be called as the voltage is equal to the product of current and Resistance. If any two parameters are known the other parameter can be calculated by using the following formula. V = I R I =V/ R …

## Capacitor in Series and Capacitor in Parallel

In this post, I had explained about the Capacitor in Series and Capacitor in Parallel combination. If you want to know about what Capacitor is and its types, check this post. Also, read: Resistors in Series & Resistors in Parallel The capacitor in Series & Capacitor in Parallel Capacitors in Series: Let Capacitance C1, C2 …

## Resistor in Series and Resistor in Parallel Combination

Resistors in Series and Resistors in Parallel Combination Resistors in Series: A combination in which resistors are connected in a sequential manner is called as Resistors in Series. A resistor in series combination possesses the same current throughout the series. This can further be explained by the following expression. Let  Req be the Equivalent Resistance. …
