Given C = 0.7 mF. R₁ = 124 Ohms, R₂ = 428 Ohms, and L = 1 H in Fig. P6.38, compute the voltage across the capacitor, Vc. 12 V (+ R2 R1 ww L

A capacitor with a capacitance of 32 microfarads is discharged through a resistance of 53 kilo-ohms.  How many milliseconds does it take for the voltage to drop to 1/e of its initial value.  Here "e" is the base of natural logarithms, about 2.718 .

PSPICE The current in a 50 µH inductor is known to be MULTISIM iL = 18te-104 A fort > 0. a. Find the voltage across the inductor fort > 0. (Assume the passive sign convention.) b. Find the power (in microwatts) at the terminals of the inductor when t = 200 ms. c. Is the inductor absorbing or delivering power at 200 ms? d. Find the energy (in microjoules) stored in the inductor at 200 ms. e. Find the maximum energy (in microjoules) stored in the inductor and the time (in milliseconds) when it occurs.

An 8 mH inductor and a 2omega resistor are in series with a 20V battery. The switch is closed for t=0 at which the current is 0. Determine the potential across the inductor and across the resistor.
