a parallel plate capacitor with circular plates of radius 1m has a capacity 10-19 F. At t =0 it is connected for charging in series with a resistor R =1mega ohm across a 2v battery. calculate the magnetic field at a point p where op = 0.5 m
Here,
C = 10-19 F
x = 0.5 m
r = 1 m
R = 106 Ω
V = 2 volt
A = π m2
Let distance between the two plates be d
Approximating a circular plate as rectangular plate
C = εoA/d
=> d = 8.85×10-12×π/10-19
=> d = 2.8×108 m
Thus, plates are far away, electric field near the first plate will be
E = q/(2εoA)
By RC circuit analysis
