In an experiment on charging of an initially uncharged capacitor, an RC circuit is made with the resistance R = 1 k Ω and the capacitor C = 1 0 4 μ F along with an ideal voltage source of 60 V. If the displacement current through the capacitor (in mA), 5 seconds after the charging has started is 4P then find the value of P. [Take, e ​ = 3 5 ​ ]

Displacement current equals the conduction current: I = R V ​ e − t / RC RC = 1000 × 1 0 − 2 = 10 s I = 60 mA × e − 1/2 = 60 × 5 3 ​ = 36 mA 4 P = 36 P = 9
