An electrical device that has a complete or continuous path that electricity can flow through.

The difference in the electric potential between two locations. In electric circuits, voltage is often used interchangeably.

A device that transforms or converts chemical energy into electrical energy or electric current.

The opposition that a conducting material or device offers to resist the flow of current. Measured in ohms (Ω).

A material, such as a metal, that offers low resistance to the flow of electric current.

The total or combined resistance of a circuit with more than one resistor.

The sum of the voltage drops (voltage differences) around a closed loop equals zero.

The flow of electric charges, usually in wires or other conductors. Measured in amperes (A).

An electric circuit with a break that prevents electricity from flowing through it.

An electric circuit where the resistance is very low or near zero, resulting in high current flow that exceeds the circuit’s design limits and can damage the components.

The amount of electrical potential energy that each unit of electric charge has. Also called potential difference. Measured in volts (V).

This law states that the current in an electric circuit is proportional to the voltage applied and inversely proportional to the resistance, or I = V/R.

An electrical device that resists the flow of electric current.

A material that is a poor conductor of electric current.

An electric circuit where the electric current can take more than one path.

A safety device in a circuit that stops the flow of current when a maximum current is exceeded and can be reset manually after the current is brought below the maximum allowed value.

A unit of electric current, equivalent to one coulomb of charge per second.

An electric circuit where the switch is connected, allowing electricity to flow through the circuit. The opposite of an open circuit.

The unit of electric potential and electric potential difference.

An instrument to measure the voltage, or potential difference, across one or more components of a closed circuit. A multimeter usually includes one of these as one of its instrument settings.

The unit of electrical resistance. A resistance of one of these means a current of one amp will flow if a voltage of one volt is applied.

An instrument with different settings that can measure current (ammeter), voltage (voltmeter), or resistance (ohmmeter).

An electric circuit where the electric current has only one path.

This law states that the sum of all currents entering a junction must equal the sum of all currents exiting that junction.

The measure of consumed energy typically used by power companies. Equivalent to the energy transferred by one kilowatt of power in one hour.
