Question

The resistance of the circular conducting wire is 120 ohm and the Resistance equivalent across AB is 55/6 Ohm. The angle subtended by the arc at the centre is

Answer 1

The angle subtended at the centre will be 0.152π  radian

Explanation:

Resistance of circulating conducting wire = 120 ohm

Resistance equivalent across AB = 55/6 ohm  

We know that:

Resistance equivalent across AB = (Resistance of circulating conducting wire per radian) (angle at centre)

So,

Angle at centre = ((55/6) × 2 π)/120

Angle at centre = 0.152 π radian
