Electricity and Circuits

 

Synopsis

 

  • Electricity is a form of energy widely used by man.

 

  • The simplest form of a circuit is when the two terminals of a cell are connected to the two terminals of a bulb through a switch.

 

  • In an electric circuit/the direction of current is taken from the positive terminal to the negative terminal of the source.

 

  • When a circuit is complete, current (charges) starts flowing. It stops flowing when the circuit breaks at a point.

 

  • A switch is used to break or complete a circuit.

 

  • Materials that allow electricity to pass through them are called conductors. Most of the metals and impure water are examples of conductors.

 

  • Materials that do not allow electricity to pass through them are called insulators. Dry wood, pure water, air and rubber are examples of insulators.

 

  • To represent an electric circuit certain symbols are being used. A list of few symbols are given below in the table.
