Correct! Wrong!

Switches, electrical plugs and sockets are mainly made of insulators, only for connecting purpose conductors are used.

#### Combination of two or more cells is called ____.

Correct! Wrong!

The combination of two or more cells is called a battery. In battery the positive terminals of one cell is connected to the negative terminal of next cell.
