What is the relationship between voltage and current in a parallel RC circuit?

• The voltage across the resistor and the capacitor is different, and the current through the resistor and the capacitor cancels each other out.

• The voltage across the resistor and the capacitor is unrelated, and the current through the resistor and the capacitor is equal to the total current flowing into the circuit.

• The voltage across the resistor and the capacitor is the same, while the current through the resistor and the capacitor adds up to the total current flowing into the circuit.

• The voltage across the resistor is higher than the voltage across the capacitor, and the current through the resistor is lower than the current through the capacitor.

How does the time constant affect the behavior of an RC circuit?

• It has no effect on the behavior of the circuit

• It only affects the resistance in the circuit

• It determines the color of the circuit

Explain the concept of phase angle in an RC circuit.

• Phase angle in an RC circuit is the current flowing through the circuit

• Phase angle in an RC circuit is the angular difference between the voltage across the resistor and the voltage across the capacitor.

• Phase angle in an RC circuit is the frequency of the voltage

• Phase angle in an RC circuit is the resistance of the capacitor

What are the key differences between a series RC circuit and a parallel RC circuit?

• In a series RC circuit, the resistor and capacitor are connected in parallel, while in a parallel RC circuit, the resistor and capacitor are not connected to each other.

• In a series RC circuit, the resistor and capacitor are connected in parallel, while in a parallel RC circuit, the resistor and capacitor are connected in series.
