Electrical power is measured in which of the following units?
AnswerWatts.
Electrical power describes the rate at which electrical energy is transferred or used.
What is the term for the flow of electrons in an electric circuit?
AnswerCurrent.
Electrical current describes the movement of electric charge through a circuit.
What is the electrical term for the force that causes electron flow?
AnswerVoltage.
Voltage is electrical potential difference. That difference provides the push that can drive current through a circuit.
In which type of circuit is the current always the same through all components?
AnswerSeries.
A series circuit provides only one path for current, so the same current passes through each component.
In which type of circuit is the voltage always the same across all components?
AnswerParallel.
Parallel branches connect across the same two electrical nodes, so each branch sees the same voltage.
