6.9 AC and DC Electric Generators

"AC" in an AC electric generator stands for

• alternating current

• alternative current

• actual current

• alternating cable

"DC" in a DC electric generator stands for

• divisible current

• direct current

• direct cable

• divine current

An electric generator

• converts mechanical energy into chemical energy

• converts chemical energy into electrical energy

• converts mechanical energy into gravitational potential energy

• converts mechanical energy into electrical energy

Select all that apply to AC electric generators.

• the direction of current changes

• the direction of current remains constant

• uses slip rings

• uses split rings

• the magnitude of induced current is constant

Select all that apply to DC electric generators.

• the direction of current remains constant

• the direction of current changes

• uses slip rings

• uses split rings

• the magnitude of induced current is constant

When increasing the number of coils and number of windings in each coil

• AC generators produce more electricity

• DC generators produce more electricity

• both AC and DC generators produce more electricity

• neither AC nor DC generators produce more electricity

Select all that apply to commutators.

• converts AC to DC

• converts DC to AC

• changes current direction every cycle

• keeps current direction constant
