What is Electricity?

Which of the following devices in your home use electricity?

• Refrigerator

• Broom

• Spoon

• Book

What do you think happens if the circuit is broken?

• The circuit will continue to work.

• The circuit will stop working.

• The circuit will work intermittently.

• The circuit will explode.

Electric current is:

• a flow of electric charge.

• a type of magnetic field.

• a form of potential energy.

• a type of chemical reaction.

Electric current is measured in which unit?

• Volts

• Amperes

• Watts

• Ohms

The brightness of a light bulb is affected by the current in what way?

• The brightness increases with more current.

• The brightness decreases with more current.

• The brightness remains the same regardless of current.

• The brightness flickers with more current.

Controlling the current in a circuit is important because:

• it ensures the safety of the circuit components.

• it increases the voltage in the circuit.

• it decreases the resistance in the circuit.

• it allows more current to flow through the circuit.

Capacitors are used in:

• Power supply circuits

• Digital watches

• Both A and B

• None of the above

We use insulators around wires because:

• They conduct electricity.

• They prevent electrical shocks.

• They are decorative.

• They increase electrical flow.

Static electricity can cause a small shock when you touch a metal object. What is this phenomenon called?

• Electromagnetism

• Static Discharge

• Magnetic Induction

• Current Electricity

What would life be like without electricity?

• Life would be more challenging without modern conveniences.

• Life would be unchanged.

• Life would be easier without technology.

• Life would be more advanced.
