Question

differentiate betwern the following:
(1)open circuit and close circuit.
(2)incandescent lamp and flourescent tubes.
(3)battery and cell.
(4)magnet and electromagnet.
(5)conductor and insulator.

Answer 1

1. when the gap between the two pins is closed , the switch is said to be closed (on) and when the gap is open it is said to be open(off)
3.cell is the source of electricity and the combination of cells is called battery
4. In normal things as pins magnet is used and in some electric things as electric motors.
5.Materials which allow electricity to flow through them are called conductors and and which do not allow it they are called insulators

HOPE THIS HELPS YOU

Answer 2

open circuit-the current does not flow.
close circuit-the current flows

battery-which can be recharged,reused.
cell-which cannot be reused,once it get exhausted there is no use in this just we need to throw.

conductor-materials which allow electricity to pass through them.good conductors of electricity.
insulator-materials which do not allow electricity to pass through it.

electromagnet-coil of soft iron
