This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. What happens when current passes through a motor's field coils?
Energy
1000 watts
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
A magnatic field is generated that makes the motor rotate - producing mechanical power.
2. What is a useful characteristic that can be used in an appliance?
Most common electrical devices are set to operate as 120/240 V.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
1000 watts
When current flows - the resulting work is energy. Current flow tends to heat whatever its moving through - which is a useful characteristic of an appliance.
3. What do you have to calculate to get the amount of electrical power?
You must multiply voltage ( involts) times current(in amperes).
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.

Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
5. How is current measured?
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
In units of Amperes

9. How can electrons be forced to move?
KW-H
Electrons can be forced to move by pushing more electrons to the wire. However - no electron can get into the wire unless an equal number of electrons is pushed out of the other end.
Most common electrical devices are set to operate as 120/240 V.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
10. What is DC?
The design that the system is able to handle total amperage needs.
Hertz - one cycle per second is equal to one hertz. Electricity is caused to flow through wires at a frequency of 60 cycles per second. This means electrons flow one direction - then in the reverse direction - repeating this cycle 60 times every seco
KW-H
Stands for direct current and it is when electrons move in one direction.
11. What voltage are common electrical devices - designed to operate as?
Most common electrical devices are set to operate as 120/240 V.
