Define current and state an equation that links current, charge and time, with units for each.
Electric current is the flow of electrical charge around a circuit. Charge(C) = Current(A) x Time(s)

What is meant by potential difference and resistance in a circuit?
Potential difference is the difference of electrical potential between two points. Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it.

What is the equation that links potential difference, current and resistance?
Potential difference = Current x Resistance

What is an ohmic conductor?
Ohmic conductors have a constant resistance - the resistance doesn't change with the current. At a constant temperature, the current flowing through an ohmic conductor is directly proportional to the potential difference.

Name one linear component and one non linear component.
Linear: Resistor, Non Linear: Diode
