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 Amperes?
Stands for alternating current and it is when electrons move in both directions.
Energy
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.
KW-H
2. What happens when current passes through a motor's field coils?
Electricity behaves as a water system. It must have pressure to push the water - and a drain to allow it to flow continuously.
Stands for alternating current and it is when electrons move in both directions.
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.
3. What does P = E x I stand for?
Watt.
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.
Power which is watt.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
4. 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
KW-H
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.
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 voltage are common electrical devices - designed to operate as?
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.
