Question

- Part A Constants A generator rotates at 75 Hz in a magnetic field of 0.055 T. It has 950 turns and produces an rms voltage of 110 V and an rms current of 70.0 A. What is the peak current produced? Express your answer to three significant figures and include the appropriate units. A LÅ 6 - O ? Ipeak = Value Units Submit Request Answer - Part B What is the area of each tum of the coil? Express your answer to two significant figures and include the appropriate units. ? PH LÅ Value - O Units] A= Submit Request Answer

Explanation / Answer

part A)

peak current = rms current * sqrt(2)

peak current = 70 * sqrt(2)

peak current = 99 A

the peak current is 99 A

part B)

let the area of each turn is A

110 = N * B * A * 2pi * f/sqrt(2)

110 * sqrt(2) = 110 * 2pi * 75 * A * 0.055

solving for A

A = 0.055 m^2

the area of each coil is 0.055 m^2
