SUMMARY

The discussion focuses on calculating the frequency for an R1, L circuit with an AC voltage source supplying an rms voltage of 115 V, where R1 is 3.35 kΩ and L is 39 mH. The rms current is specified as 31.33 mA. The relevant equations include the relationship between rms current, rms voltage, and impedance, specifically using the formula irms = vrms / XL, where XL is the inductive reactance calculated as XL = ωL. The solution involves converting angular frequency (ω) to frequency (f) using the formula f = ω / (2π).

PREREQUISITES
  • Understanding of AC circuit analysis

Homework Statement



In the circuit shown, the AC voltage source supplies an rms voltage of 115 V and the circuit has R1 = 3.35 kΩ and L = 39 mH.

a) At what frequency will the rms current be 31.33 mA (milliamperes)?

Homework Equations



irms=vrms / XL

The Attempt at a Solution



Did you remember to convert from ω to f?[PLAIN]https://wug-s.physics.uiuc.edu/cgi/courses/shell/common/showme.pl?cc/DuPage/Phys1202/summer/homework/Ch-23-24/RL_phase/RL.jpg

do you know the formula relating Irms, Vrms, Z (impedance) ?
use that ...
 
Z= (sqrt R^2 + XL^2) = (sqrt R^2 +(wL)^2)
Vrms,R = IrmsR
Vrms,L = IrmsXL = Irms(wL)
wL= 2pi*f*L


these are the formula i used and i solve for f thanks for the help
