Define electrical conductivity.
Electrical conductivity is a measure of a material's ability to conduct electric current. It is the reciprocal of electrical resistance and is typically measured in siemens per meter (S/m).

See lessDefine electromotive force (EMF).
Electromotive force (EMF) is the energy per unit charge supplied by a source, such as a battery or generator, to drive electric current through a circuit. It is measured in volts (V).

See lessWhat is the formula for calculating resistance in a circuit?
Resistance (R) in an electrical circuit is calculated using Ohm's Law: R = V/I, where V is the voltage across the resistor and I is the current flowing through it.

See lessWhat is the difference between series and parallel circuits?
In a series circuit, components are connected end-to-end, and the same current flows through each component. In a parallel circuit, components are connected across the same voltage source, and the voltage across each component is the same.

See lessWhat is the purpose of a fuse in an electrical circuit?
A fuse is a safety device used to protect electrical circuits from overcurrents and short circuits. It melts or breaks the circuit when the current exceeds a predetermined threshold.
