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 is the amount of power used over a period of time?
A magnatic field is generated that makes the motor rotate - producing mechanical power.
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.
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
Energy
2. What type of system does electricity behaves as?
Most common electrical devices are set to operate as 120/240 V.
120/240 V service.
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
3. What is the basic unit to measure electrical power?
The design that the system is able to handle total amperage needs.
KW-H
Watt.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
4. What is DC?
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
Energy
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
Stands for direct current and it is when electrons move in one direction.
5. Electrical Power is the product of what?
Stands for alternating current and it is when electrons move in both directions.
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
Energy
60 cycles per second.
6. What happens when current passes through a motor's field coils?
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
Power which is watt.
A magnatic field is generated that makes the motor rotate - producing mechanical power.
Energy
7. What is going on in a wire conductor with free electrons?
8. What is voltage or electromotive force?
A magnatic field is generated that makes the motor rotate - producing mechanical power.
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
You must multiply voltage ( involts) times current(in amperes).
9. What is the measurement unit of electron movement
Stands for direct current and it is when electrons move in one direction.
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
Watt.
1000 watts
10. What does P = E x I stand for?
Stands for direct current and it is when electrons move in one direction.
A magnatic field is generated that makes the motor rotate - producing mechanical power.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
Energy
11. How can electrons be forced to move?
Most common electrical devices are set to operate as 120/240 V.
A magnatic field is generated that makes the motor rotate - producing mechanical power.
From an electricians - pov - electricity is the movement of electrons. Electrons are atomic particles found in every substance. An electron has one main characteristic which is a negative electrical charge.
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.
12. What is 1 kilowatt equal too?
Stands for alternating current and it is when electrons move in both directions.
1000 watts
The design that the system is able to handle total amperage needs.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
13. What is the amperage that can be measured with a ammeter?
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
Energy
Power which is watt.
120/240 V service.
14. What is WATT?
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
The basic unit used to measure electrical power.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
Stands for alternating current and it is when electrons move in both directions.
15. What does an appliance need to function properly?
A magnatic field is generated that makes the motor rotate - producing mechanical power.
