An RLC series circuit with R = 5 Ω, C = 10 μF, and a variable inductance L has an applied voltage V = 110 V with a frequency of 60 Hz. L is adjusted until the voltage across the resistor is a maximum. Find the following: a. XL = ______________ b. XC = ______________ c. I = ______________

Consider the RC circuit in Figure 2 below. Assuming the switch has been open for a long time before it is closed, fill in a table providing the current through each component and the voltage across each component immediately after the switch is closed, and a very long time after the switch is closed. Next, figure out the time constant for the circuit. (Hint: Assign currents to each branch. Set up the necessary KVL and KCL equations. Eliminate all but one variable to get an equation for just one of the currents. You shouldn’t have to solve this equation to recognize the time constant!)

Which of the following statements is true of an open component in a series circuit? a.. The circuit current will be higher than normal. b. The voltage drop across the component will be lower than normal. c. The voltage drop across the component will be higher than normal. d, The resistance of the component will be lower than normal.
