For a given plate-voltage, the plate current in a triode is maximum when the potential of
The grid is positive and plate is negative
The grid is positive and plate is positive
The grid is zero and plate is positive
The grid is negative and plate is positive
When grid is given positive potential more electrons will cross the grid to reach the positive plate P. Hence current increases

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
