Explanation: 

Detailed explanation-1: -The electric current in wires is made up from millions of minute, negatively charged particles called electrons, which drift along the wires. As a result the charge flows around the circuit.

Detailed explanation-2: -Current can only flow in a closed circuit. A circuit is closed when there is no obstruction to the flow of electric current through the circuit.

Detailed explanation-3: -Wires are made of metals, which are conductors. Conductors have some electrons that are rather free to move. Electric current (electricity) is a flow or movement of these electrons through the conductor.
