 Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between EMF and Voltage. The basic difference between EMF and voltage is that EMF is energy given to the charge and voltage is the energy needed for the movement of one unit charge from one point to another.

In today’s post, we will have a detailed look at both EMF and voltage with the detailed compare them to find their differences. So let’s get started with Difference Between EMF and Voltage.

#### Difference Between EMF and Voltage

EMF

• The energy provided to the one coulomb of charge is called EMF.
• its measuring units is volts.
• Its formula is E=I(R+r). In this equation, R is outer resistance and r is inner resistance of circuitry
• The device that produces the EMF called a transducer. it is such a module that transforms any type of energy in electrical energy.
• In case of having loop created through conductive material then force given on charges in the path to move on make emf.
• The module that has 2 terminals emf value can get from these points
• The electromotive generation instruments examples are solar, photodiodes cell, battery
• The magnetic fields also make emf.
• Its mechanical expression is ε=w/q

Voltage

• Voltage is the energy required by the charge to move from one location to another.
• Its formula is V=IR. and define J/C here J is joule and C is coloumb
• Its symbolic representation is V. Its other units are millivolts, kilovolts,
• Voltmeter used to finds its value
• Volts help to find electromotive force and potential difference
• Volts is generating through electrical field
• The value of voltage can be found between two points.
• The source that generates voltage is electric and magnetic fields. So friends that is a complete post about the difference between EMF and voltage if you have any questions ask in comments. Thanks for reading, Have a good day.
