Question
Explain construction of Daniel cell.
✓
Answer
The zinc and copper plates are connected by an electric wire through a switch and voltmeter.
The solution in two containers are connected by salt bridge $(U-$shaped glass tube containing a gel of $KCl \ or \ NH_4NO_3$ in agar$-$agar$).$
When switch is on, electrical circuit is complete as indicated by the deflection in the voltmeter.
The circuit has two parts, one in the form of electrical wire which allows the flow of electrons and the other in the form of two solutions joined by salt bridge. In solution part of the circuit, the electric current is carried by movement of ions.
