- An inductor of 2 henrys, a resistor of 16 ohms and a capacitor of 0.02 farads are connected in series with an e.m.f. of E volts. At t=0 the charge on the capacitor and current in the circuit are zero. Find the charge and current at any time t> 0 if E= 300 (volts). Suppose q (t) and i(t) be the instantaneous charge and current respectively at time t. By Kirchhoff's law's, the differential equation for the circuit is: L + Ri+²=E; with di dt dq- q (0) = 0, i(0) = q (0) = 0 [Note: i = dtarrow_forwardFor the network of Figure 4, find the mathematical expressions for the transient behavior of the voltage v, and the current i, following the closing of the switch at position 1 at t = O sec. Find the mathematical expressions for the voltage ve and current i, as a function of time if the switch is thrown into position 2 at t = 20 msec.

Find the charge flowing into the device for t >= 0. Also find the total charge entered into the device at t = 0.05s. My Comments: I just don't understand this at all. Can you explain it what it means?arrow_forward
