A 0106A current is charging a capacitor that has square plat

A 0.106-A current is charging a capacitor that has square plates 4.60 cm on each side. The plate separation is 4.00 mm. (a) Find the time rate of change of electric flux between the plates. V·m/s (b) Find the displacement current between the plates. A

Solution

the time rate of change of electric flux

a)

phi = q/apsalan

dphi/dt = 1/apsalan*dq/dt = i/apsalan

= 1*0.106)/(8.85*10^-12) = 11977401129.9 = 1.19*10^10

b)

displacement current = apsalan*(dphi/dt = 0.106 A
