Question

Suppose that you wish to construct a simple ac generator having 64 turns and an angular velocity of 377 radians/second (this is the frequency point of 60 Hz). A uniform magnetic field of 0.050 T is available. If the area of the rotating coil is 0.01 m 2, what is the maximum output voltage?

Answer 1

Answer:

$\epsilon_{max} =12.064\ V$

Explanation:

Given,

Number of turns, N = 64

angular velocity, ω = 377 rad/s

Magnetic field, B = 0.050 T

Area, a = 0.01 m²

maximum output voltage = ?

We know,

$\epsilon_{max} = NBA\omega$

$\epsilon_{max} = 64\times 0.05\times 0.01\times 377$

$\epsilon_{max} =12.064\ V$

The maximum output voltage is equal to 12.064 V.
