RC Circuit

Combination of circuit |RC and LR Circuit| Phasor diagram

In an RC circuit while charging, the graph of 1n i versis time is as shown by the dotted line in the diagram figure. Where i is the current. When the value of the resistance is doubled, which of the solid curve best represents the variation of 1n i versus time

A certain series RC circuit is formed using a resistance R , a capacitor without dieiectric having a capacitance C=2F and a battery of emf E=3V . The circuit is completed and it is allowed to attain the steady state. After this, at t=0 , half the thickness of the capacitor is filed with a dielectric of constant K=2 as shown in the figure. The system is again allowed to attain a steady state. What will be the heat generated (in joule) in the capacitor between t=0 and t=oo ?

Parallel RC and Parallel RL Circuit

Show that time constant (tau = RC) of R - C circuit has the dimensions of time.

In a series RC circuit, R = 30 ohm, C = 0.25 mu F , V = 100 V, omega = 10000 rad//s . Find the current in the circuit and calculate the voltage across the resistor and capacitor. Is the algebraic sum of these voltages more than the source voltage ? If yes, resolve the paradox.
