Direction of Electric current in a circuit

# data[].attributes.body
-Electrons move from negative terminal to positive terminal.
-Conventional current - from positive to negative.

# data[].attributes.body
A circuit which does notprovide a complete path for the flow of electric current, from the source to the device and back to the source is known as closed circuit

# data[].attributes.body
The whole combination of a cell, connecting wires and the device to be operated  connected in a manner to complete path for flow of charges from one terminal to other terminal of the cell through  the device is called an electric circuit.

The path of flow of electrons is known as an electric circuit.
-path made by electric wires.
-Force by the voltage that makes the electron move is provided by the cell.
-Flowing electrons provide energy so that the device work

-Mechanical energy is converted into electrical energy.
-PRINCIPLE- Electromagnetic induction
A magnet is repeatedly moved to and fro across a stationary conducting material.
- No physical connection between the conductor and the magnet hence called as induced current.

Converts soar energy into electrical energy
ADVANTAGES:
-No pollution
USES:
-Calculators, wrist watches
- Large number of solar cells connected together to obtain solar panel arrays
-panels are used to power street lights, produce large amount of electricity for use in space stations and artificial satellites
-Electricity stored during day can be used during nights
