Which particle gets transferred when you charge objects by friction?

atom

electron

neutron

proton

If two charges repel each other, the two charges must be

Positive and neutra

Positive and negative

positive and neutral

negative and negative

An object becomes charged when the atoms in the object gain or lose

electrons

protons

neutrons

all of the above

If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

friction destroyed electrons in the rod.

the silk has become negatively charged.

protons have moved to the rod.

glass attracts more protons.

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

friction.

convection.

induction.

conduction.

Objects that have opposite charges

are attracted to each other, and the force between the objects pulls them together.

are attracted to each other, and the force between the objects pushes them apart.

are repelled by each other, and the force between the objects pulls them together.

are repelled by each other, and the force between the objects pushes them apart.

15.

What can you say about the current in the series circuit?

it splits across the components

it changes constantly

it is different in different places

it is the same everywhere

16.

Which component provides the energy for the charges?

cell

bulb

switch

ammeter

17.

If the ammeter says the current is 5A, what is the current flowing through one bulb?

2.5A

10A

18.

What is the name of the device which measures current?

(a)

19.

Current is measured in

Volts

Watts

Seconds

Amps

20.

If the switch was opened, what would happen?

the ammeter would measure a current flowing

current would no longer flow, so everything would be off

the bulbs would stay on because they're connected to the cell

the bulbs would burn out and catch fire

21.

What causes a decrease in current?

Adding another bulb

increasing resistance

decreasing voltage from the supply

decreasing the resistance

22.

If the current flowing through the cell is 2A, what is the ammeter reading?

23.

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 is divided between the three light bulbs.

Circuit

Insulator

Resistance

Conductor

25.

Pick the correct sentence.

This circuit will work because it is a closed circuit.

Energy will freely flow in this circuit.

This circuit will not work because there is no energy source.

This circuit will not work because there is no switch.
