Question

Review problem. Determine the maximum magnetic flux through an inductor connected to a standard electrical outlet with ΔVrms = 115 V and f = 55.0 Hz.

Answer 1

Answer:

Φ = 0.47 Wb

Explanation:

Given that

Vrms = 115V

f= 55 Hz

The maximum voltage V given as

$V_{max}= \sqrt2\ V_{rms}$

The maximum current I given as

$I=\dfrac{V_{max}}{2\pi fL}$

Maximum magnetic flux

Φ = I L

$\hi=\dfrac{\sqrt2\ V_{rms}}{{2\pi f}}$

Now by putting the values

$\hi=\dfrac{\sqrt2\ \times 115}{{2\pi \times 55}}$

Φ = 0.47 Wb
