What is the impedance of a purely resistive circuit?
Z = R
Z = jX
Z = R + j0
Z = 0
In a purely resistive circuit, the impedance (Z) is equal to the resistance (R), as there is no reactance involved.

Q: What is the impedance of a purely resistive circuit?
Solution: In a purely resistive circuit, the impedance (Z) is equal to the resistance (R), as there is no reactance involved.
Steps: 4
Step 1: Understand that a circuit can have resistance and reactance. Resistance is the opposition to current flow, while reactance is the opposition due to capacitors and inductors.
Step 2: In a purely resistive circuit, there are no capacitors or inductors. This means there is no reactance.
Step 3: Since there is no reactance, the impedance (Z) of the circuit is only due to the resistance (R).
Step 4: Therefore, in a purely resistive circuit, the impedance (Z) is equal to the resistance (R).
