What is the purpose of a circuit breaker?
Answer: To protect circuits from overcurrent by tripping and interrupting power
A circuit breaker is a resettable overcurrent protection device that trips to interrupt power when current exceeds the rated capacity.
How many watts does a circuit operating at 120V and 15A produce?
Answer: 1,800 watts
Power = Voltage × Current = 120V × 15A = 1,800 watts.
What is the purpose of a ground wire in an electrical system?
Answer: To provide a safe path for fault current back to the source
The ground wire (equipment grounding conductor) provides a low-resistance path for fault current, causing protective devices to trip.
What does EMF stand for in electrical theory?
Answer: Electromotive Force
EMF (Electromotive Force) is the energy per unit charge that drives current through a circuit, measured in volts.
A 20-amp circuit at 240 volts serves a load. What is the resistance of the load?
Answer: 12 ohms
Using Ohm's Law: R = V/I = 240/20 = 12 ohms.
What type of circuit has only one path for current to flow?
Answer: Series circuit
In a series circuit, all components are connected end-to-end in a single loop with only one current path.
