What is Ohm's Law?
Ohm's Law defines the relationship between voltage, current, and resistance in an electrical circuit.
What does the term 'ampacity' refer to?
Ampacity refers to the maximum amount of electric current a conductor or device can carry before sustaining immediate or progressive deterioration.
What is the purpose of grounding in electrical systems?
Grounding provides a safe path for the discharge of electrical currents to prevent electric shock and fires.
Which of the following is the unit of electrical power?
Electrical power is measured in watts, which is the rate at which energy is used or produced.
What is the primary difference between AC and DC current?
The primary difference between AC (Alternating Current) and DC (Direct Current) is the direction in which the current flows.
What is the function of a circuit breaker?
A circuit breaker is used to protect an electrical circuit from damage caused by overcurrent or short circuits.

Which of the following is a common type of electrical conductor?
Conductors are materials that allow the flow of electrical current, with copper being the most common type.
What is the purpose of a transformer?
A transformer is used to increase or decrease voltage in an alternating current (AC) circuit.
What does the term 'impedance' refer to in an AC circuit?
Impedance is the total opposition to current flow in an alternating current (AC) circuit, similar to resistance in a DC circuit.
