Which of the following are the passive elements?

Select the correct answer(s).

(0/0)

Explanation

When the element is not capable of delivering energy independently, are called as passive element. Both resistor and bulb are the passive elements and they can't increase the energy level of a circuit.

Rms value is defined based on which of the following?

Select the correct answer(s).

(0/0)

Explanation

Rms (Root mean square) value is defined based on heating effect of wave-forms. The value at which heat dissipated in AC circuit is same as the heat dissipated in DC circuit is called rms value, provide both AC and DC circuits have equal value of resistanc

What is form factor?

Select the correct answer(s).

(0/0)

Explanation

The form factor of an alternating current waveform (signal) is the ratio of the rms (root mean square) value to the average value. Here the average value is the mathematical mean of absolute values of all points on the waveform.

The field at any point on the axis of a current carrying coil will be

Select the correct answer(s).

(0/0)

Explanation

A continuous current in a current carrying coil is divided into multiple current elements. Using the superposition principle and the Biot-Savarts law, each discrete element generates its own magnetic field and when it is integrated with each field that p

An electric field line and an equipotential surface are

Select the correct answer(s).

(0/0)

Explanation

For parallel conducting plates like those in a capacitor, the electric field lines are perpendicular to the plates hence they are parallel to each other and the equipotential lines are parallel to the plates.

An equipotential surface is one which has all points at _____________ potential.

Select the correct answer(s).

(0/0)

Explanation

Equipotential surface means potential is constant everywhere. No work is done to move a charge. The equipotential surface are thus orthogonal to the direction of lines of electric field.

The resistivity of the conductor depends on

Select the correct answer(s).

(0/0)

Explanation

The resistivity is a property of material, defined as the resistance between two opposite faces of a cube of a material of unit volume. That is why resistivity is only the unique property of material and it does not depend upon the dimension of any piece
