Question

A boy records that 4000 joules of work are required to transfer 10 coulombs of charge between two points of a resistor of 50 Ω. Find the current passing through it.


Iz anyone still zinda??

Answer 1

Answer:

Work done=4000J

electric charge=10C

Resistance=50ohm

potential difference, V=W/Q=4000/10=400J/C

current,I=V/R=400/50=8A

Answer 2

Answer:

Electric current = 8A

Explanation:

W.D = 4000 J

q = 10 C

R = 10 Ω

Electric potential V = W/q

                               = 4000/10

                               = 400 V

V = IR

∴ I = V/R

    = 400/50

    = 8 A

Electric current passing through the resistor = 8A
