Transformers
- A transformer is a device that changes voltage from one value to another.
- Power at the input end is equal to the power at the output end.
- Only the voltage will increase or decrease.
Principle:-
Transformers work on the principle of Mutual induction.
Mutual Induction :- Suppose there are 2 inductors if some current flows through coil(1) ,there will be change in the current as a result there will be change in the magnetic flux, as a result there will be change in the magnetic flux in the coil (2) and because of which emf is induced in the coil(2).

Charge of electron,{tex} q_1=-1.6\times 10^{-19}\ C{/tex}
Charge of proton, {tex}q_2=+1.6\times 10^{-19}\ C{/tex}
Distance between them,{tex} r=0.8\times 10^{-15}\ m{/tex}
Coulomb's force is given by :
{tex}F=k\dfrac{q_1q_2}{r^2}{/tex}
{tex}F=9\times 10^9\times \dfrac{1.6\times 10^{-19}\ C\times 1.6\times 10^{-19}\ C}{(0.8\times 10^{-15}\ m)^2}{/tex}
{tex}F=360\ N{/tex}
Hence, the force between the proton and electron is 360 N and it is attractive in nature.

Wheatstone bridge
- Wheatstone bridge is a special arrangement of resistors as shown in the figure.
- There are 4 resistances R1,R2,R3and R4 arranged in such a manner thatthere is a galvanometer placed between the points B and D.
- The arm BD is known as galvanometer arm. AC is known as battery arm.
- And circuit is connected to the battery across the pair of diagonally opposite points A and C.
- According to Wheatstone bridge principle:-
- If (R1/R2)=(R3/R4), then Bridge is said to be balanced.
- If the bridge is balanced there is no current flowing through the galvanometer arm.
