Question

30j of workdone on 10C of charge.then find current? at 2 sec​

Answer 1

Answer:

Current = 5A

Explanation:

Workdone (W) = 30J

Charge (Q) = 10C

Time(t) = 2s

W = VQ

V = W / Q

Potential difference (v)  =  30 / 10  = 3V

heat = VIT

Current (I) = ?

Heat = workdone

30J = 3 x I x 2

30 = 6I

I = 30 / 6

I = 5A

Current = 5A
