Question

a battery sets up an electric field of 25 N/C inside a uniform wire of length 2m and a resistance of 5 ohm . find current through the wire.

Answer 1

R= 5 ohms
L= 2m
E= 25 N/C

using ohms law V=IR

I =V/R

V=ed
V= 25×2= 50V

since L is 2m so d=2 because electrons have to cover that distance.

I=50/5
=10A

Answer 2

Hey dear,

◆ Answer-
I = 10 A

◆ Explanation-
# Given-
E = 25 N/C
d = 2 m
R = 5 ohm

# Solution-
Potential difference is calculated by -
V = E.d
V = 25 × 2
V = 50 V

Current flowing through wire is -
I = V/R
I = 50/5
I = 10 A

Therefore, current flowing through wire is 10 A.

Hope it helps...
