An RLC circuit consists of a 48 Ω resistor, a 200 μF capacitor and an inductor. The rms current is 2.5A when the circuit is connected to a 120 V, 60 Hz outlet. What is the inductance, in mH?

A series RLC circuit is driven by an oscillating emf. The current in the circuit is ahead of the emf. Which of the following changes to the circuit, when done independently of one another, will bring the angular frequency of the circuit closer to the resonant frequency? I. Increase the capacitance. II. Decrease the inductance. III. Increase the resistance.

Light with horizontal polarization and initial intensity I0 is incident upon two polarizing filters. The first filter has a transmission axis measured 20° from the horizontal. The intensity of the light through both filters is 30% of its initial intensity. What is the angle between the transmission axis and the horizontal for the second filter?

One of Maxwell’s equations can be written as
