Answer to Question #151321 in Physics for Harsh

Question

Find the rms value, average value and form factor of resultant current in a circuit with simultaneous dc supply of 5A and ac supply with magnitude of 5A.

Answer 1

1) $I_{rms}=\sqrt{\frac{5^2+(0.707\cdot5)^2}{2}}=4.3(A)$

2) $I_{avr}=\frac{5+0.637\cdot5}{2}=4.1(a)$

3) Form Factor$=\frac{I_{rms}}{I_{avr}}=\frac{4.3}{4.1}=1.05$
