Name the commercial unit of electric energy

Content Curator

The commercial unit of electric energy is the kilowatt-hour (kWh). Electric energy is the energy produced by the movement of electric charge. It can take the form of electromagnetic radiation, such as light, or it can be stored in electric fields and magnetic fields. Electric energy can be harnessed to power a wide range of technologies, including electrical appliances, lighting, transportation, and communication systems.

The properties of electric energy include:

Ability to transfer energy through electrical conductors.
Ability to be transformed into other forms of energy.
Ability to be stored in electric fields and magnetic fields.

Kilowatts Explained

A kilowatt-hour (kWh) is a unit of energy commonly used to measure the amount of electricity used by households and businesses. It is equal to the amount of energy consumed by a 1 kilowatt (kW) appliance over a period of 1 hour. For example, if a 100-watt light bulb is turned on for 10 hours, it would consume 1 kilowatt-hour of energy.

Two parallel plate capacitors X and Y are connected in series to a 6 V battery. They have the same plate area and same plate separation but capacitor X has air between its plates, whereas capacitor Y contains a material of dielectric constant 4. Calculate the capacitances of X and Y, if the equivalent capacitance of the combination of X and Y is \( 4 \, \mu\text{F} \). Calculate the potential difference across the plates of X and Y.
