RLC Circuit: Calculate R Given V,f,P

Click For Summary
SUMMARY

The discussion focuses on calculating the resistance (R) in an RL circuit given a voltage (V) of 100 V, frequency (f) of 50 Hz, and power (P) of 6 watts. The relationship between these parameters can be established using the formula P = V^2 / R, which allows for the determination of R. By rearranging the formula, R can be calculated as R = V^2 / P, resulting in R = (100^2) / 6, leading to a resistance value of approximately 1666.67 ohms.

RLC Circuit - Given V,f,P find R?
You have an inductor plugged into a 100 V AC source with a frequency of 50 hertz. There is a power of 6 watts and this can modeled as an LR circuit with R being the resistance from the Inductor. Calculate R.
