AC FUNDAMENTALS

Front

Rotating a magnet near a conductor produces a current because

Back

The electrons are repelled and attracted due to the law of charges

Front

The strength of a generated voltage depends on three things. Which of the following is NOT one of them?
- The speed at which the magnetic lines of flux pass through the coil
- The size of the conductor
- The strength of the magnetic field
- The number of turns in the coil of wire

Back

The size of the conductor

Back

Is the number of times a generator rotates in one second

Front

RMS stands for root mean square and is

Back

A value of AC voltage produce the same amount of power as a like DC voltage

Front

A sine wave can be defined as

Back

A graphical representation of what's happen to voltage AC circuit over time

Inductance can be increased by: Increasing the conductor size, Increasing capacitance in an AC circuit, Coiling the conductor, Reducing resistance

Back

Coiling the conductor
