Question

Column I gives three physical quantities. Select the appropriate units for these from the choices given in column II. Some of the physical quantities may have more than one choice.

Column-I	Column - II
a) Capacitance	d) Ohm second
b) Inductance	e) Coulomb${}^2$ joule${}^{-1}$
c) Magnetic induction	f) Coulomb volt${}^{-1}$
	g) Newton (ampere/metre)${}^{-1}$
	h) Volt second (ampere)${}^{-1}$

• A. a-e,f; b-d,h; c-g
• B. a-h; b-d; c-e
• C. a-e; b-g,h; c-g
• D. a-e,f; b-d,h; c-d,e

Answer 1

Answer: (A)

a-e,f; b-d,h; c-g

Capacitance is charge per unit volt.

Volt has unit of work per unit chage.

So capacitance has units of charge square per unit energy.

Inductance is defined as volt per unit rate of change of current and voltage per unit current is resistance, so inductance is ohm second.
