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.

A bee doesn’t have to know a flower has nectar or not. The nectar itself attracts the bee. Nectar is a sugar rich liquid whose main function is to attract pollinators like bees. Mainly the scent works ( here by scent i mean picking up the odour by sensing molecules in air and not actually smelling it). But apart from scent, there are other ways like the colour pattern of the flower and a lot more way
