What is the current in a circuit if the charge passing through each point is 20 C in 40 s?

Answer»

SOLUTION :Given, Charge = Q = 20 C, Time = t = 40 SEC
As we know that current is the RATE of flow of charge or by ohm.s law we can say
Charge [Q] = current [I] `xx` time [t]
`I=Q/trArrI=20/40=1/2amp.=0.5amp.`
