What is the impedance of a circuit with a resistor of 4Ω and an inductor of 3Ω at resonance? (2022)

Step 1: Understand that impedance is a measure of how much a circuit resists the flow of electric current.
Step 2: Know that in a circuit with a resistor and an inductor, the total impedance can change depending on the frequency of the current.
Step 3: Recognize that at resonance, the inductive reactance (which is related to the inductor) and the resistance (from the resistor) balance each other out.
Step 4: At resonance, the impedance of the circuit is equal to the resistance of the resistor alone.
Step 5: Since the resistor has a value of 4Ω, the impedance at resonance is also 4Ω.
