The unit of current is Ampere (A)

• The unit of current is Ampere (A)

• Current is the flow of electric charge in a circuit

• 1 Ampere is equal to 1 Coulomb per second

• Commonly used prefixes for current are milliampere (mA) and microampere (μA)

The unit of resistance is ohm (Ω).

• The unit of resistance is represented by the symbol Ω.

• It is named after the German physicist Georg Simon Ohm.

• Resistance is measured in ohms, which is the amount of opposition a material offers to the flow of electric current.

RPM stands for Revolutions Per Minute, a unit of measurement used to describe the speed at which an object rotates around a fixed axis.

• RPM is commonly used in the automotive industry to describe the speed of a car engine's crankshaft.

• It is also used in the context of power tools, such as drills and saws, to indicate how fast the tool is operating.

• RPM can be calculated by counting the number of revolutions a rotating ob

Electromotive Force

• EMF stands for Electromotive Force

• It is the electrical potential difference that causes current to flow in a circuit

• Measured in volts (V)

• Commonly used in batteries to provide power
