Question

Which of the following formula states the relation between current, potential difference and resistance?

A.

R =V/I

B.

R = VI

C.

I = VR

D.

R = I/V

Correct option is A

The correct answer is (a) R = V/I.
· The formula R = V/I represents Ohm's Law, which states that the resistance (R) in a circuit is equal to the ratio of the potential difference (V) across the circuit to the current (I) flowing through it.
· In simpler terms, it describes the relationship between voltage, current, and resistance in an electrical circuit.
The full expression of Ohm's Law is: V = IR, where:
· V is the potential difference (voltage),
· I is the current, and
· R is the resistance.
Information Booster:
· Ohm's Law is fundamental to understanding how electrical circuits function.
· It helps in determining how much current flows through a circuit for a given voltage and resistance.
· In an electric circuit, if the voltage increases and resistance remains constant, the current increases as well.
