Answer 2

Question:

In transferring 1.5 C charge through a wire, 9 J of

work is needed. Find the potential difference across the wire.

Answer:

6 V

Solution:

Given:

Charge (Q) = 1.5 C

Work (W) = 9 J

Formula:

W = Q × V

Let's Solve:

Work = Charge × Volt

9 = 1.5 × Volt

Volt = 9/1.5

Volt = 9 × 10 / 15

Volt = 90/15

Volt = 6

Therefore,

$6volt = \: ans$
