A series R-C circuit is connected to AC Voltage source. Consider two cases: (A) when is without a dielectric medium and
when
is filled with dielectric of constant 4 . The current
through the resistor and voltage
across the capacitor are compared in the two cases. Which of the following is/are true?
In case (b) capacitance (c) will be more. Therefore, impedance will be less. Hence current will be more.
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
