Basics of Electricity

What is electricity?

• Electricity is the movement of water molecules.

• Electricity is a form of renewable energy.

• Electricity is a type of energy storage.

• Electricity is the flow of electric charge.

What is the unit of electric current?

• Ampere

• Volt

• Watt

• Ohm

What is the difference between conductors and insulators?

• Insulators are used to enhance electrical flow; conductors are used to block it.

• Conductors and insulators are the same; they both allow electrical flow.

• Conductors are always made of metal; insulators are always made of plastic.

• Conductors facilitate electrical flow; insulators hinder it.

What is a circuit?

• A circuit is a method of measuring voltage.

• A circuit is a closed loop that allows electric current to flow.

• A circuit is a device that stores energy.

• A circuit is a type of electrical appliance.

What is the role of a battery in a circuit?

• To convert electrical energy into mechanical energy.

• The role of a battery in a circuit is to supply electrical energy.

• To regulate the flow of current in the circuit.

• To store electrical energy for later use.

What is voltage?

• Voltage is the electric potential difference between two points.

• Voltage is the measure of current flow.

• Voltage is the resistance in a circuit.

• Voltage is the power consumed by an appliance.

What is the purpose of a switch in a circuit?

• To increase the voltage in a circuit.

• To control the flow of electricity in a circuit.

• To convert AC to DC in a circuit.

• To store electrical energy for later use.

What happens when you connect a light bulb to a battery?

• The light bulb turns off.

• The battery drains instantly.

• The light bulb explodes.

• The light bulb lights up.

What is static electricity?

• Static electricity is a type of current that flows continuously.

• Static electricity is the movement of electrons through a conductor.

• Static electricity is the accumulation of electric charge on the surface of objects.

• Static electricity is the energy produced by chemical reactions.

What are the safety precautions when working with electricity?

• Use metal tools for better conductivity

• Work in wet conditions for cooling

• Keep power on to test circuits easily

• Wear PPE, use insulated tools, avoid wet conditions, turn off power, and test circuits.
