Question 1

What is the difference between static and current electricity?

Answer 1

Static Electricity: Electrons gather in one place and move in different directions
Current Electricity: Electrons flow in one controlled path

Question 2

What are the parts of a simple circuit?

Answer 2

Energy Source: Where electrical energy comes from (e.g., battery).
Load: Converts electrical energy into other forms of energy
Conducting Wires: Pathway for electrons to flow.
Switch: Controls the flow of electrons by breaking or completing the circuit.

Question 3

How and why does a short circuit occur?

Answer 3

When electricity takes a path with low resistance, bypassing the load.

Question 4

What is the difference between a primary cell and a secondary cell?

Answer 4

Primary cell: Cannot be recharged (e.g., AA battery).

Secondary cell: Can be recharged (e.g., phone battery).

Question 5

What is electrical energy?

Answer 5

The energy produced by the flow of electrons.

Question 6

What is direct current (DC)?

Answer 6

Electrons flow in one direction through the circuit from the negative side to the positive side of a circuit.

Question 7

What is alternating current (AC)?

Answer 7

Electrons move back and forth, changing direction. It’s used for long-distance energy distribution.

Question 8

How do electrical generators work?

Answer 8

-They convert kinetic energy into electrical energy
-Spinning a coil of wire inside a magnetic field
-Causing electrons to move through the wire

Question 9

What is the purpose of a motor?

Answer 9

To convert electrical energy into mechanical energy which makes objects move

Question 10

What is the use of a resistor?

Answer 10

Limits or reduces the amount of electricity flowing through a circuit
