Exam 18: Series Alternating-Current Circuits

The reference phasor for a series a.c. circuit is the __________ phasor

The reference phasor in any a.c. circuit is normally drawn along the

To convert a voltage phasor diagram into an impedance diagram, we must __________ voltage phasors __________ the reference phasor.

The load current lags the supply voltage by 90 degrees for __________ loads

If the voltage drop measured across the resistive component of a series R-C circuit is 90 V and the voltage drop measured across the capacitive component is 120 V, the supply voltage must be

The voltage appearing across a series R-L circuit is the __________ of the voltage-drops across the resistive and inductive components
