Question

an appliance of resistance 22 ohms is connected across a 'v' of 220 v. find the amount of charge flowing in 10 mins

Answer 1

Resistance,R = 22ohms.

Potential difference,V = 220V

Time = 10 minutes = 600s.

By ohms law, we have

V = IR

I = V/R

I= 220/22.........(V = 220V & R=22)

I = 10A

Hence, current is 10 ampere

Now, We know that I = Q/t..........(Q= charges
moved &
t= time
taken)
Q= I*t
Q= 10*600
Q= 6000C

Hence, Charges moved is 6000C
