Weekly Quiz Competition

Question 1
1 / -0

'In a closed electric circuit, the electric current passes from one terminal of the electric cell to the other terminal.' The statement is

A
True

B
False

C
Maybe true

D
Maybe false

Solution

The statement is true. In a closed electric circuit, the electric current passes from positive terminal of the electric cell to the negative terminal.
Question 2
1 / -0

Match the following -
1. Electric Cell a. metal cap
2. Positive Terminal b. metal disc
3. Negative Terminal c. produce electricity

A
1-a, 2-b, 3-c

B
1-c, 2-a, 3-b

C
1-a, 2-c, 3-b

D
1-c, 2-b, 3-a

Solution

Electric Cell - produces electricity
Positive Terminal - metal cap
Negative Terminal - metal disc
Question 3
1 / -0

The bulb glows only when _________ flows through it.

A
Current

B
Light

C
Air

D
Water

Solution

The bulb glows only when current flows through the circuit and current heats the filament of bulb and bulb gives light.
Question 4
1 / -0

Why does an electric bulb fuse?

A
Break in bulb's filament.

B
Break in bulb's outer glass cover.

C
Poor quality of bulb.

D
None of the above.

Solution

An electric bulb may fuse due to a break in its filament. A break in the filament of an electric bulb means a break in the path of the current between the terminals of the electric cell.Therefore, a fused bulb does not light up as no current passes through its filament.
Question 5
1 / -0

For which of the following arrangements will the bulb glow?

A
(b) and (c)

B
(a) and (f)

C
(d) and (e)

D
(a) and (d)

Solution

To glow the bulb, circuit should be closed.
In fig (a) and (f), the circuit is a closed circuit. Hence, the bulb will glow.
Question 6
1 / -0

How many terminals does an electric bulb have?

A
One

B
Two

C
Three

D
Four

Solution

An electric bulb has 2 terminals - one positive and the other negative.
Question 7
1 / -0

Sometimes an electric bulb does not glow even if it is connected to the cell. Why?

A
Bulb has fused.

B
Electric cell has stop producing electricity as the chemicals in the electric cell got used up.

C
The wires are not properly connected.

D
Any of the above reasons could be the answer.
Solution
Sometimes an electric bulb does not glow even if it is connected to the cell. It can be due to the following reasons -
- Bulb has fused.
- Electric cell has stop producing electricity as the chemicals in the electric cell got used up.
- The wires are not properly connected.
Question 8
1 / -0

Match the following
1. Circuit a. Chemical
2. Wire b. Direction of current
3. Bulb c. Connector
4. Cell d. Filament

A
1-c, 2-b, 3-d, 4-a

B
1-b, 2-c, 3-d, 4-a

C
1-b, 2-c, 3-a, 4-d

D
1-b, 2-a, 3-d, 4-c

Solution

Circuit - Direction of current
Wire - Connector
Bulb - Filament
Cell - Chemical
Question 9
1 / -0

In an electric circuit, the direction of current is taken to be from the __________ to the __________ terminal of the electric cell.

A
Negative, Positive

B
Positive, Negative

C
Positive, Positive

D
Negative, Negative

Solution

As can be seen in the figure.
In an electric circuit, the direction of current outside the cell is taken to be from the positive to the negative terminal of the electric cell.
Question 10
1 / -0

____________ material allows electric current to flow through it easily.

A
Rubber.

B
Non-metals

C
Plastic

D
Metals

Solution

Metals are good conductors of electricity; hence, they allow electric current to flow through them easily.
For example: Silver, copper, etc
