​Buzzer - turns electricity into sound

Multiple Choice

Circuit B works, but circuit A does not work. It is beacuse _____ .

• Circuit A does not have switch

• Circuit B's cells are connected properly

• Circuit B has more power than A

• Circuit A's bulb is connected in wrong way

Multiple Choice

What would happen when the switch is opened ?

• nothing, the light bulbs would still work because there is a complete path

• the light bulbs would not work because the path was broken

• the battery would loose energy

• the wires would be cooled f air

Multiple Choice

What is the function of this device ?

• turn the chemical energy into electrical

• turn electrical into chemical energy

• turn electrical into sound

• turn electrical into light

Multiple Choice

What is the function of this device ?

• turn chemical energy into electrical

• turn electrical into chemical energy

• turn electrical into sound

• turn electrical into light

Multiple Choice

What is the function of this device ?

• turn chemical energy into electrical

• turn electrical into chemical energy

• turn electrical into sound

• turn electrical into light

Multiple Choice

This is a switch. it is used to turn on/off the electricity in circuit.

What is the condition of this switch ?

• opened switch

• closed switch

Multiple Choice

What does an ammeter measure ?

• resistance

• voltage

• current

• energy

Multiple Choice

To measure current in circuit, ammeter should be connected in _____ .

• series

• parallel

Multiple Choice

The diagram shows a circuit including a lamp, an electric bell and three switches S1, S2 and S3. The lamp and bell are not faulty.

The bell is ringing but the lamp is not lit. Which switches are closed?

• S1 only

• S1 and S3

• S1 and S2

• S

Multiple Choice

All the things are the example of _____ .

• conductor

• insulator

Multiple Choice

Which one below is NOT an insulator ?

• wooden block

• woolen cloth

• metal spoon

• rubber band

Multiple Choice

Read the scale.

• 0.44 A

• 0.48 A

• 0.60 A

• 0.80 A

Multiple Choice

Read the scale.

• 62 A

• 64 A

• 68 A

• 70 A

Multiple Choice

Read the scale.

• 2.2 A

• 2.4 A

• 3.0 A

• 4.0 A

​ADDING/REMOVING cells into circuit will affect to voltage and current flow in that circuit.

​

Adding more cells will produce large voltage, then the current flows in circuit increases.​

​ADDING/REMOVING lamps in circuit will affect to brightness of lamp and current flow in that circuit.

​

Adding more lamps with the constant battery in circuit will cause the decrease current flows in circuit, the lamp will be dimmer.

Multiple Choice

In a series circuit, adding more bulbs will make the light becomes

• dimmer (dull)

• brighter

Multiple Choice

Adding more cell (batteries) in a line to a circuit, the bulbs will

• get brighter

• will become less bright

• will blink

• will explode

Multiple Choice

The picture shows an electrical circuit. This circuit is a series circuit because:

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current has more than one path to flow through

Multiple Choice

Which of the following could make the bulb in circuit A brighter? 

• adding another light bulb
• putting in a switch 
• adding another battery
• reversing the direction of the battery
