Question

The ratio of electric field vectors E and magnetic field vector H has the dimensions of
(a) resistance
(b) inductance
(c) capacitance
(d) product of inductance and capacitance

Answer 1

The ratio of electric field vectors E and magnetic field vector H has the dimensions of (a) resistance. Because dimensions of electric field vectors E is volt/metre. Dimension of magnetic field vector H is Ampere/metre. The ratio of vectors E and vector H is Volt/Ampere. In accordance with Ohm's law, ratio of voltage and current strength is resistance.
