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 unit commonly used to measure electrical energy?
Voltage and current in a circuit. That is - voltage(in volts) times current (in amperes) equals power (in watts) P=E x I
60 cycles per second.
Stands for alternating current and it is when electrons move in both directions.
KW-H
2. What is the amperage that can be measured with a ammeter?
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.
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.
3. How is current measured?
In units of Amperes
The design that the system is able to handle total amperage needs.

4. What is going on in a wire conductor with free electrons?
5. What is the measurement unit of electron movement
Watt.
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
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
6. How can electrons be forced to move?
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
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.
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.
