Electricity - Chapter 7.1 - 7.4

Question 1

What is a conductor

Answer 1

is a substance or material that allows electricity to flow through it

Question 2

What is an insulator

Answer 2

An insulator is a material which does not easily allow heat and/or electricity to pass through it.

Question 3

What is a convention current

Answer 3

Convection currents are heat-driven cycles that occur in the air, ocean, and mantle.

Question 4

What is a closed circuit

Answer 4

A closed circuit is a circuit in which the path is complete and there is a flow of current in the entire path.

Question 5

What is static electrical charge

Answer 5

Static electricity is the result of an imbalance between negative and positive charges in an object.

Question 6

.

Answer 6

.

Question 7

Distinguish between conductors and
insulators.

Answer 7

Materials that permit electricity or heat to pass through it. Materials that do not permit heat and electricity to pass through it.

Question 8

Provide examples for both conductors and insulators

Answer 8

Conductor: silver, aluminium, and iron.
Insulators: paper, wood, and rubber.

Question 9

Distinguish between parallel and series
circuits.

Answer 9

In a series circuit, the same amount of current flows through all the components placed in it. On the other hand, in parallel circuits, the components are placed in parallel with each other due to which the circuit splits the current flow.

Question 10

How to calculate voltage

Answer 10

The formula - Voltage = current x Resistance

Question 11

Don’t forget to memorise all of the symbols and learn how to draw the circuits.

Answer 11

Press the four so it pops up once you have learnt everything.
