Question

a coil of 100 turns each of area 0.02 m2 ; is rotated at 100 rps in a plane perpendicular to a magnetic field of induction 3.5 × 10 -2 T .what is the rms value of emf induced in the coil​

Answer 1

Dear Student,

◆ Answer -

E(rms) = 4.95 V

● Explanation -

# Given -

n = 100 turns

A = 0.02 sq.m

B = 3.5×10^-2 T

ω = 100 rps

# Solution -

RMS value of EMF is given by formula -

E(rms) = n.A.B.ω/√2

E(rms) = 100 × 0.02 × 3.5×10^-2 × 100 / √2

E(rms) = 4.95 V

Hence, rms value of emf induced in the coil 4.95 V.

Thanks dear. Hope this helps you...
