Inserting dielectric in capacitor

What is a dielectric material?

• An insulating material that can be polarized by an electric field.

• A conducting material that can be polarized by an electric field.

• A material that allows electric current to flow through it easily.

• A material that does not respond to an electric field.

Name one example of a dielectric material.

What is the purpose of a dielectric material in a capacitor?

• To increase capacitance

• To reduce voltage

• To store energy

• To decrease capacitance

What happens to the capacitance of a capacitor when a dielectric material is inserted?

• The capacitance of a capacitor remains the same.

• The capacitance of a capacitor increases.

• The capacitance of a capacitor decreases.

• The capacitance of a capacitor becomes zero.

What is a battery?

• A battery is a device that stores electrical energy and converts it into mechanical energy.

• A battery is a device that stores chemical energy and converts it into electrical energy.

• A battery is a device that stores mechanical energy and converts it into electrical energy.

• A battery is a device that stores electrical energy and converts it into chemical energy.

What are the two terminals of a battery called?

• top and bottom

• plus and minus

• positive terminal and negative terminal

• anode and cathode

What is the function of a battery in an electrical circuit?

• Provide electrical energy

• Generate electrical energy

• Control the flow of electricity

• Store electrical energy

What is a capacitor?

• A type of battery used in electronic devices.

• A device that converts electrical energy into mechanical energy.

• A component that amplifies electrical signals.

• An electronic component that stores and releases electrical energy.

What are the two plates of a capacitor made of?

• liquid material

• magnetic material

• insulating material

• conductive material

How does a capacitor store and release electrical energy?

• A capacitor stores electrical energy by accumulating and storing electric charge on its plates. When a voltage is applied across the capacitor, electrons are forced onto one plate and pulled from the other plate, creating an electric field between the plates. This electric field stores the energy. When the capacitor is connected to a circuit, it releases the stored energy by allowing the charge to flow from one plate to the other, creating an electric current.

• A capacitor stores electrical energy by converting it into mechanical energy.

• A capacitor stores electrical energy by generating magnetic fields.

• A capacitor stores electrical energy by converting it into heat energy.
