Commutator.—A circuit changer, or switch. The collector of currents on a dynamo.
Compound Winding.—A method of increasing or decreasing the energy developed in a dynamo in proportion to the demand.
Conductivity.—Is the reciprocal to resistance, and applies to that property of any substance whereby the passage of electricity through it is effected with the least opposition.
Conductors.—Substances which most freely permit electricity to pass.
Connections.—Wires, &c., completing the circuit between different apparatus.
Contact Breaker.—The electric lighting equivalent for a gas tap.
Coulomb (Q).—The Unit of quantity, which passes in one second of an ampère current.
