Question

what is ohms law and principle of electric motor

Answer 1

At the constant temperature the current flowing through a conductor is directly proportional to the proportional difference accros it's ends called ohm's law.


Principal of motor
A motor works on the principal that when a rectangular coil is placed in a magnetic field and current is pass through it, a force act on the coil which rotate it continuously.

I hope this will help you

Answer 2

$\textbf{Answer :}$


$\huge\textbf{Ohms law :}$
 

According to it electric current (I) is directly proportional to Voltage (V).

i.e.

$V$ $\alpha$ $I$

If we remove the sign of directly proportional then we have to use a constant i.s. R (Resistance).

i.e.

$V\:=I\:R$

or

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

or

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



$\huge\textbf{Principle of electric motor :}$


An electric motor is based on the principle that whenever a carrying conductor placed in a magnetic field it experiences force.
