A sinusoidal voltage Δv = 45.0 sin(100t), where Δv is in volts and t is in seconds, is applied to a series RLC circuit with L = 170 mH, C = 99.0 µF, and R = 60.0 Ω. e) What If? For what value of the inductance (in H) in the circuit would the current lag the voltage by the same angle ? as that found in part (d)? f) What would be the maximum current (in A) in the circuit in this case?

The charge on the capacitor of an LC circuit with capacitance C and inductance L obeys the following equation. Find the maximum current in the circuit. q= Q cos [t/(LC)0.5] Q Q/(LC) 0.5 zero QQ²/(LC) 0.5 imax 1/(LC) 0.5

In the circuit shown in the Figure with 3.0 mH for the inductance and 6.0 uF for the capacitance, S1 has been closed for a long enough time so that the current reads a steady 3.50 A. Suddenly, S2 is closed and S1 is opened at the same instant. What is the maximum charge that the capacitor will receive?  What is the current in the inductor at this time? At an instant when the charge on the capacitor is 0.1 mC, what is the current in the inductor? At an instant when the charge on the capacitor is 0.1 mC, what is the rate at which the current in the inductor is changing?

An LR circuit consists of an inductor with L = 2.5 x 10* H and a resistor with R 5.3 connected in series to an oscillating source of cmf. This source generates a voltage given by E= Emax Sin(@t) with E a) What is the maximum current in the circuit? b) What is the phase angle of the current? c) What is the average power dissipated in the resistor? %3D 0.40 V and w =6x 10* rad/s.

An inductor and a resistor are connected in series. When connected to a 60-Hz, 90-V (rms) source, the voltage drop across the resistor is found to be 55 V (rms) and the power delivered to the circuit is 18 W. (a) Find the value of the resistance. 22 (b) Find the value of the inductance. H

Your RL circuit has a characteristic time constant of 21.5 ns, and a resistance of 5.40 MΩ. A. What is the inductance (in H) of the circuit? B. What resistance (in MΩ) should you use (instead of the 5.40 MΩ resistor) to obtain a 1.00 ns time constant, perhaps needed for quick response in an oscilloscope?
