Question

14. The unit of inductive reactance is -
(a) Henry
(b) Farad
(WBSCTE 2013]
(d) Joule
(C) Ohm​

Answer 1

The unit of inductive reactance is Ohm.

• The inductive reaction, XL, of the coil is a sign of the coil's ability to generate a self-generated voltage.
• The expression takes into account the degree of change in the current in terms of frequency (f) and inductor size according to its value (L). However, to make the coil, many earrings are used. This causes coil resistance due to the length of the wire. It shows that the internal resistance of the coil is expressed systematically by showing a small resistor in the coil series. The coil represents the active properties of the inductor, while the resistor represents its opposing properties.

Answer 2

Answer:

The correct answer for the question ' The unit of inductive reactance is', option (C) Ohm

Explanation:

Inductive reactance is an opposition to the current flow that is created by a coil when it is connected to an AC supply circuit.

1 ohm can be defined as 'transferring a current of 1 ampere when put through a potential difference of 1 volt'.

The unit of -

• Inductance is henry
• Electrical capacitance is farad
• Work and energy is joule
