ET CH4: AC Circuit part 1

What is a sinusoid?

• A signal that has the form of the sine or cosine function

• A type of resistor

• A type of capacitor

• A type of inductor

What is a phasor?

• A complex number that represents the amplitude and phase of a sinusoid

• A type of circuit element

• A type of voltage

• A type of current

What is the difference between time domain and phasor domain?

• Time domain represents voltage and current as a function of time, while phasor domain represents them as magnitude and phase

• Time domain represents voltage and current as magnitude and phase, while phasor domain represents them as a function of time

• Time domain represents resistance, while phasor domain represents reactance

• Time domain represents reactance, while phasor domain represents resistance
