PD, emf & S.I base units

Question 1

What is emf

Answer 1

• Electromotive force is the energy on the charge carriers, provided by the cell or battery, transferring any other forms of energy into electrical.
• So that then as the charge carries move through the circuit, the electrical energy is transferred into other forms.

Question 1

What is PD?

Answer 1

The energy transferred by the charge carries to the components, transferring electrical energy into other forms of energy

Question 2

define the volt

Answer 2

One volt is the potential difference across a component when 1J of energy is transferred per unit of charge passing through the component. 1V is 1J of energy transferred per coulomb of charge.

Question 3

What are the seven s.i base units?

Answer 3

Time - s
Length - m
Mass - kg
Current - A
Temperature - K
Amount - mol
Luminous intensity - candela
