What is voltage? - The potential difference between two points that
represents the energy released in the transfer of a unit charge, measured in volts
(V).
What is the SI unit for voltage? - Volt (V).
How is voltage related to energy? - Voltage is the amount of energy per
unit charge, measured in joules per coulomb.
What is the role of a voltmeter? - A voltmeter measures the voltage across
two points in a circuit.
What is electromotive force (EMF)? - The energy that causes current to
flow through a circuit.
What is current? - The flow of electric charge per unit time, measured in
amperes (A).
What is the SI unit for current? - Ampere (A).
What is resistance in an electric circuit? - Resistance is the opposition to
the flow of current through a conductor, measured in ohms (Ω).
