Explanation

Joule is a derived unit of energy, not a base unit.

Kelvin (temperature), Kilogram (mass), and Ampere (current) are SI base units.

Explanation

The kilowatt-hour (kWh) is a unit of energy commonly used to measure electricity consumption.

It represents the amount of energy used when a device with a power rating of 1 kilowatt operates for 1 hour. 

Additional information 

Energy/Work: Measured in joules (J).

Charge: Measured in coulombs (C).

Pressure: Measured in pascals (Pa).

Electric current: Measured in amperes (A).

Electric resistance: Measured in ohms (Ω).

Temperature: Measured in kelvin (K).

Torque: Measured in newton metres (N m).

Velocity: Measured in meters per second (m/s).

Acceleration: Measured in meters per second squared (m/s²).

Explanation

• The unit of pressure equal to 1 newton per square meter (N/m2) is called a Pascal (Pa).
• It is named after French mathematician and physicist Blaise Pascal.

Explanation

Electric flux is measured in Coulombs C, and surface area is measured in square meters (m2).

The SI unit of electric flux density is coulomb per square meters (C/m2).

Explanation

The symbol of the SI unit Kelvin is K.

It is the base unit of temperature in the International System of Units.

It is used to measure thermodynamic temperature.

Explanation

Ozone is an allotropic form of oxygen which plays an important role in absorbing ultra-violet radiation of the sun. 

Explanation

• The Second is a fundamental unit of time in the International System of Units (SI).
• It is one of the seven base units that are used to derive all other units.

Explanation

The standard SI unit for magnetic dipole moment is the ampere-square meter (A⋅m²).

It can also be expressed in terms of energy and magnetic field strength, resulting in joules per tesla (J/T), which is equivalent to A⋅m². 

Explanation

A current is a flow of electric charge.

In electric circuits this charge is often carried by moving electrons in a wire.

The SI unit of electric current is the ampere.

Explanation

Speed is defined as.

The rate of change of position of an object in any direction.

Speed is measured as the ratio of distance to the time in which the distance was covered
