A resistor has first two colours as Red and Blue then its resistance (in ohm) is equal to
26
16
28
18
As we learnt
Colour bands A and B -
Indicate the first two significant figures of resistance in ohm.
-
Red - 2
Blue-6
Hence resistance is 26
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
