How to Calculate Resistance in a Circuit

What is the formula to calculate resistance in a circuit?

The formula to calculate resistance in a circuit is V = I * R. Where V is voltage, I is current, and R is resistance.

Answer:

The formula to calculate resistance in a circuit is V = I * R.

When dealing with electrical circuits, it is important to understand how to calculate resistance. The formula V = I * R, known as Ohm's Law, is essential for determining the resistance within a circuit. This formula states that the voltage (V) across a circuit is equal to the current (I) flowing through it multiplied by the resistance (R) of the circuit.

By rearranging the formula, we can calculate the resistance of a circuit by dividing the voltage by the current. This calculation allows us to determine the amount of resistance present in the circuit based on the given voltage and current values.
