Question

what is emf and volt ?​

Answer 1

Answer:

Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field

           E = WORK DONE/ CHARGE

VOLT is unit of POTENTIAL DIFFRENCE. defined as amount of work done to move a charge from one point to another point

     also, v  = WORK DONE/ CHARGE      

EMF IS electromagnetic flux  in magnetism defined as no. of magnetic field lines

$\huge{\boxed{\boxed{\tt{\purple{EMF}}}}}$

• Electromotive force (EMF) is the measure of energy supply to each coulomb of charge.
• It is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field.

Formula :-

$E = \frac{W}{Q}$

where

• E = electromotive force
• W = work done
• Q = charge

$\huge{\boxed{\boxed{\tt{\purple{Volt}}}}}$

• The volt (V) is the Standard International (SI) unit of electric potential, or EMF.
• A potential of one volt appears across a resistance of one ohm when a current of one ampere flows through that resistance.

Formula:-

$V= \frac{I}{R}$

where

• V = voltage
• I = current
• R = resistance

Hope it helps.

All the best!
