Question
A plant consumes $100 \mathrm{kW}$ of power at 0.9 pf lagging. If the load current is $200 \mathrm{A} \mathrm{rms}$, find the load voltage.
Step 1
Step 1: We know that power (P) is given by the formula $P = V_{rms} \cdot I_{rms} \cdot pf$ where $V_{rms}$ is the root mean square voltage, $I_{rms}$ is the root mean square current and $pf$ is the power factor. Show more…

An industrial load consumes $100 \mathrm{kW}$ at 0.8 pf lagging. If an ammeter in the transmission line indicates that the load current is $200 \mathrm{A} \mathrm{rms}$, find the load voltage.
A plant consumes $20 \mathrm{kW}$ of power from a $240-\mathrm{V}$ rms line. If the load power factor is 0.9 lagging, what is the angle by which the load voltage leads the load current? What is the load current phasor if the line voltage has a phasor of $240\underline{/0_{\circ}}V rms?$
A plant consumes $60 \mathrm{kW}$ at a power factor of 0.75 lagging from a $240-\mathrm{V} \mathrm{rms} 60-\mathrm{Hz}$ line. Determine the value of the capacitor that when placed in parallel with the load will change the load power factor to 0.9 lagging.
