Question

if 320J of heat is produced in 10s in a 2 Ω resistor find the amount of current flowing through the resistor

Answer 1

Answer:

heat =i²rt

320=i²*2*10

320=i²*20

320/20=i²

i²=16

i=4

Explanation:

put the values in the formula of heat energy then u'll get ur answer

hope it will help you

Answer 2

Explanation:  We know

Potential difference = charge of electron/time

V = Q/t = 320/10 = 32 v

Resistance, R = 2 omega

By ohm’s law

V = IR

I = V/R

I = 32/2 = 16 A

Hence amount of current flowing through the resistor is 16 A
