Question #204449

The current in a series circuit of R = 50 and L= 50 mH lags the applied voltage by 80 °,the angular frequency w is:

Select one:

a. 945 rad/s

b. 473 rad/s

c. 709 rad/s

d. 405 rad/s

e. 567 rad/s

Expert's answer

"\\omega=\\frac{R}{L}\\\\\\omega=\\frac{50}{0.05}=1000\\frac{rad}{s}"
