a. electron        b. proton        c. neutron        d. atom


2. A device that stores chemical energy and converts it into electric energy when connected in a circuit:

a. electric switch        b. bulb        c. cell        d. metallic wire


3. A circuit that provides multiple paths to the current to flow:

a. series        b. parallel        c. open        d. short


4. The type of circuit used in domestic wiring:

a. series        b. parallel        c. open        d. short


5. A device used to open or close an electric circuit:

a. battery        b. bulb        c. switch        d. wire


6. Increasing the number of batteries in a series circuit:

a. increases the brightness of the bulbs

b. decreases the brightness of the bulbs

c. converts the series circuit to parallel circuit

d. stops the flow of current through the circuit


7. The current has only one path to flow through:

a. series circuit        b. parallel circuit        b. open circuit        d. close circuit



9.2 Write short answers.


1. What is static electricity?

Ans.

When the charge at rest is gathered on an object, it is known as static electricity.


2. Is series circuit preferably used in home wiring?

Ans.

No, series circuit is not used in home wiring. Because if a fault happens at any part of the circuit, it stops the flow of current in the whole circuit.


3. What is current electricity?

Ans.

When the positive terminal of battery is connected to its negative terminal through a metallic (copper) wire, charge being to flow through the wire. The electricity produced by the flow of charge is called current electricity.


4. What types of charges repel each other?

Ans.

Like charges repel each other.


5. Name a few components of electric circuit.

Ans.

Electric cell or battery, key (switch), conductors (wires) and bulb.
