What is the relationship described by Ohm's Law?
Answer: Voltage = Current x Resistance
Ohm's Law states that Voltage (V) equals Current (I) multiplied by Resistance (R): V = IR.
Which of the following materials is the best electrical conductor?
Answer: Copper
Copper is an excellent electrical conductor, which is why it is widely used in electrical wiring.
What does a capacitor do in an electrical circuit?
Answer: Stores electrical energy in an electric field
A capacitor stores electrical energy in an electric field between two conductive plates separated by an insulating material.
In a parallel circuit, what remains the same across all branches?
Answer: Voltage
In a parallel circuit, voltage is the same across all branches, while current divides among branches based on their resistance.
What type of circuit is created when a wire accidentally connects two points that should not be connected?
Answer: Short circuit
A short circuit occurs when current bypasses the intended path through a low-resistance connection, potentially causing excessive current flow.
What is the standard household voltage in the United States?
Answer: 120 volts
Standard U.S. household outlets provide 120 volts AC at 60 Hz.
