Question

What is the peak current when the rms current is \[1.04\,\mathrm{A}\]?

Options

• \[0.74\,\mathrm{A}\]

• \[1.47\,\mathrm{A}\]

• \[1.04\,\mathrm{A}\]

• \[212\,\mathrm{A}\]

Answer 1

Peak current is \[i_m=\sqrt{2}I\]. With \[I=1.04\,\mathrm{A}\], this gives approximately \[1.47\,\mathrm{A}\].
