Question

Calculate the current flowing through a wire of resistance 7.5Ω connected to a battery of potential difference 1.5V.

Answer 1

Answer:

0.2 A

Explanation:

Given, R = 7.5 Ω, V = 1.5 V

From Ohm's Law, V = I × R

Current in wire I = V / R = 1.5 / 7.5

= 1.5 / 7.5 × 10 / 10

= 15 / 75

Answer 2

Answer:

The current flowing through the wire is 0.2A.

Explanation:

We will solve this question through Ohms law.

Ohm's law describes the relationship between current, voltage, and resistance. It states that the current flowing through the conductor is directly proportional to the voltage applied to it. i.e.

$V\propto I$

$V=IR$            (1)

V=voltage applied to the conductor

I=current flowing through the conductor

R=resistance of the conductor

As per the question,

V=1.5V

R=7.5Ω

By putting the value of V and I in equation (1) we get;

$1.5=7.5\times I$

$I=0.2A$

Hence, the current flowing through the wire is 0.2A.
