Electrostatic Potential and Capacitance — Physics STD 12 Science — Question

The velocity of X-rays having wavelength 1 Å will be :

1 micro coulomb =

Which decay increases the atomic number?

If a charged particle kept at rest experiences an electromagnetic force:

From Maxwell’s hypothesis, a charging electric field gives rise to:

If the current is doubled, the deflection is also doubled in:

An inductor, a resistor and a capacitor are joined in series with an AC source. As the frequency of the source is slightly increased from a very low value, the reactance.

On increasing the temperature of a conductor, its resistance increases because(a) Relaxation time decreases(b) Mass of the electrons increases(c) Electron density decreases(d) None of the above

The conduction current is same as displacement current when source is:
