The video tutorial explains a derived SI unit, which is defined as the charge transported in one second by a current of 1 ampere. It highlights the distinction between basic and derived units, focusing on the relationship between charge, time, and current.

What distinguishes a derived SI unit from a basic SI unit?

• Derived units are simpler than basic units.

• Derived units are used only in physics.

• Derived units are combinations of basic units.

• Derived units are based on fundamental constants.

Which of the following is an example of a derived SI unit?

• Second

• Newton

• Kilogram

• Meter

How is a derived SI unit defined in terms of charge?

• As the charge transported in one minute by a current of 1 ampere.

• As the charge transported in one second by a current of 1 ampere.

• As the charge transported in one hour by a current of 1 ampere.

• As the charge transported in one second by a current of 2 amperes.

What is the relationship between charge, time, and current in a derived SI unit?

• Charge equals time multiplied by current.

• Charge equals current divided by time.

• Charge equals current multiplied by time.

• Charge equals time divided by current.

In the context of derived SI units, what does 1 ampere represent?

• A unit of charge

• A unit of time

• A unit of current

• A unit of energy
