Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 4.
Pure AC resistive circuit
For a purely AC resistive circuit, the voltage and current are in the same phase.
Hence, the power factor (cosϕ) is unity.
The power in an AC circuit is given by:
P = VI cosϕ = positive value
For pure resistive load, cosϕ=0
Hence, P = VI = Power in the DC circuit
Therefore, the expression for power is the same as the DC circuit.
