A closed path that allows electrons to flow from an energy source.

The rate at which electric charge flows through a circuit, measured in amperes (A).

The difference in electric potential energy per unit charge between two points in a circuit. It is measured in volts (V).

A property of a material that resists the flow of electric current. It converts electrical energy into other forms of energy like heat or light.

An electric circuit is a closed path; electrons flow along it, powered by energy sources.
In a circuit connected to a cell, electrons move slowly from the negative terminal to the positive terminal in the external circuit.
Electric fields in operating circuits transmit energy nearly at the speed of light.
Electric current is the rate of electric charge flow in a circuit, measured in amperes (A) using an ammeter.
Electrical resistance is a substance property that slows down electric current, converting electrical energy into other types.
Potential difference, or voltage, is the difference in electrical potential energy per unit charge between two points in a circuit; measured in volts (V) using a voltmeter.

Question 1: Compare and contrast a water tap and an electrical switch.
Question 2: Refer to Figure 11.15; explain why a D cell lasts longer than other cells.
