Answer the following questions about an AC generator. Circle the correct answer.

Question

Answer the following questions about an AC generator. Circle the correct answer. [1] The voltage of the AC generator is created by rotational motion/EM induction. [2] An AC generator provides electric energy. Electric energy is due to the separation of excess change/rotating fields/movement of electrons. [3] The terminals of the AC generator are of constant/changing polarity. [4] When the inner coil is spun faster, the output voltage of the source increases/decreases/stays the same. [5] For one cycle, the voltage of an AC power source averages to more than half of its maximum value/less than half of its maximum value/zero. [6] For one cycle, the voltage squared of an AC power source averages to more than half of its maximum value/less than half of its maximum value/zero. [7] When the AC generator is operating a circuit, the electrons in the circuit are attracted to the source terminal that faces the North Pole/faces the South Pole/is positively charged/is negatively charged.

Explanation / Answer

1.

When a current carrying coil is placed in the magnetic field, EMF is induced (voltage) in that coil.

Hence, it can be concluded that the voltage in the generator is due to electromagnetic induction.
