Resistance: This could be defined as the opposition  or retarding force to the flow of current in a circuit. It is measured in Ohms.

Capacitance: The ability of a system of electrical conductors and insulators to store electrical charge when a potential difference is existing between the conductors. It is the mathematically expressed in Farad.

Inductance: The ability of a circuit, coil that causes an e.m.f to be set up due to a rate of change of current in the circuit or coil. It's unit is Henry.
