Open Ended

Explain how the phase relationship between current and voltage differs in capacitive, inductive, and resistive AC circuits.

Multiple Choice

Why is resonance in RLC circuits important for applications such as radio receivers and communication systems?

• Because it maximizes current and allows selection of specific frequencies

• Because it minimizes voltage in the circuit

• Because it increases resistance to maximum value

• Because it eliminates the need for capacitors
