Two Zener diode ( A and B) having breakdown voltage of 6V and 4V respectively, are connected. The voltage V0 variation with i/p voltage linearly increasing with time is given by: (V at t= 0)
Option: 1
Option: 2
Option: 3
Option: 4
Till input voltage Reaches No zener is in Breakdown Region So
Then Now when
changes between
One Zener with
will Breakdown are P.D. across This zener will become constant and Remaining Potential will drop. acro Resistance in series with
Zener.
Now current in circuit increases Abruptly and source must have an internal resistance due to which. Some potential will get drop across the source also so correct graph between and t. will be
We have to Assume some resistance in series with source

5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
