We determined the constants R and L of a coil by placing it in series with a standard resistor of 10 ohms and reading the voltages on the terminals of Rs, the coil and the series circuit complete. What are the values of R and L for the following voltage readings at 60 Hz:(adsbygoogle = window.adsbygoogle || []).push({});

Vrs = 20; Vcoil = 22,4; Vt = 36

Answer:

R = 5 ohms

L = 26,5mH

I find the current

Vrs = I . Zr

20 = I . 10 I = 2A

Now I do not know how to find R and L
