Question

How is the voltage phasor \[V_R\] related in phase to the current?

Options

• Voltage is in phase with the current \[(\phi=0^\circ)\].

• Voltage lags the current by \[\dfrac{\pi}{2}\].

• Voltage leads the current by \[\dfrac{\pi}{2}\].

• Current lags the voltage \[(\phi<0)\].

Answer 1

Across a resistor R, the voltage is in phase with the current. The phase difference for this component is \[\phi=0^\circ\].
