Question

glows.
2. Match the column
Column A
Column B
Covering of switches, appliances, plugs socket is
made of insulator
It is a simple device that either breaks the circuit or
completes it
When the terminals of the bulb are connected with
that of the electric cell by wires
because it does not allow current to pass through them so
we do not get shock if we touch them
electric switch
The current passes through the filament of the bulb This
makes the bulb glow
An electrician use rubber gloves while repairing an
electric switch at your home
is a device which converts Chemical
energy into electric energy
electric cell
Because it is an insulator and it prevent electric shock​

Answer 1

Answer:

a) Conductor allows the current to pass through it.

(b) Insulator does not allows the current to pass through it.

(c) Electric cell metal cap is a positive terminal.

(d) Electric cell metal disc is a negative terminal.

(e) A electric bulb with broken filament is called a fused bulb.

(f) An electric cell has four terminals.

(g) If the filament of the bulb is broken, the bulb will not glow.

(h) Air is good conductor of electricity.

(i) Themocol is an insulator.

(j) When the positive of bulb is connected with positive of the cell and negative of bulb is connected with negative of cell, the bulb glows.

(k) When the positive of bulb is connected with negative cell and negative of bulb is connected with positive of cell, the bulb does not glows
