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 do you have to calculate to get the amount of electrical power?
KW-H
Stands for direct current and it is when electrons move in one direction.
You must multiply voltage ( involts) times current(in amperes).
120/240 V service.
2. What is electricity really?
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.
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
KW-H
120/240 V service.
3. What do you need to take into account when installing a electrical system?
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
The design that the system is able to handle total amperage needs.
In a wire conductor - there are billions of loose or free electrons - all safely in place in their fields. They're distributed evenly throughout the wire.
KW-H
4. What is a useful characteristic that can be used in an appliance?
Stands for alternating current and it is when electrons move in both directions.
In units of Amperes
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.
Amps or just A - is the measurement in units of the amount of electric current that flows. The rate of electron flow determines the number of amperes in a circuit. The rate of electron flow determines the number of amperes in a circuit.
5. What is the amperage that can be measured with a ammeter?
The design that the system is able to handle total amperage needs.
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
The electrical current flow or amperage - the rate of electron flow that passes through a cross section of wire.
60 cycles per second.
6. What is AC?
Stands for alternating current and it is when electrons move in both directions.
You must multiply voltage ( involts) times current(in amperes).
Stands for direct current and it is when electrons move in one direction.
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.
7. What happens when current passes through a motor's field coils?
In a wire conductor - there are billions of loose or free electrons - all safely in place in their fields. They're distributed evenly throughout the wire.
Watt.
A magnatic field is generated that makes the motor rotate - producing mechanical power.
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
8. What does the positive-negative attraction relate too?
You must multiply voltage ( involts) times current(in amperes).
The behavior of positive and negative charges is very similar to the behavior of the two poles in a magnet.
60 cycles per second.
In a wire conductor - there are billions of loose or free electrons - all safely in place in their fields. They're distributed evenly throughout the wire.
9. What type of Voltage is required for new homes to have?
120/240 V service.
1000 watts
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

You must multiply voltage ( involts) times current(in amperes).
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
12. Electricity flows through wires In what frequency?
60 cycles per second.
