An RL circuit with L = 3.20 H and an RC circuit with C = 3.05 μF have the same time constant. (a) If the two circuits have the same resistance, R, what is the value of R? | ΚΩ (b) What is this common time constant? ms

Consider a series RC circuit as in the figure below for which R = + E R (a) Find the time constant of the circuit. S 6.50 MQ, C = 6.70 μF, and E = 25.5 V. (b) Find the maximum charge on the capacitor after the switch is thrown closed. μC (c) Find the current in the resistor 10.0 s after the switch is closed. μA

An ECG monitor must have an RC time constant less than 1.00 × 102 μs so it can measure variations in voltage over small time intervals. If the resistance of the circuit (due mostly to that of the patient’s chest) is 0.85 kΩ, what is the maximum capacitance of the circuit in F?

23 The shown RLC circuit with a - resistor, a 50 driven by the voltage E(t) = 0.07t² V. E In(t) 1 100 = R www C Find the general solution of the corresponding homogeneous equation (complementary solution) forI. Use A and B for the arbitrary constants. 25 Hinductor, and a F capacitor is 22
