Question

In the figure below, R = 19.0 ohm, C = 4.90 mu F, and L = 20.0 mH. The generator provides an emf with rms voltage 75.0 V and frequency f = 530 H. What is the rms current? 3.8013 A What is the rms voltage across R? 72.2247 V What is the rms voltage across C? 232.96 V What is the rms voltage across L? 253.173 V What is the rms voltage C and L together? V What is the rms voltage across R, C and L together? V At what rate is energy dissipated by R? W At what rate is energy dissipated by C? W At what rate is energy dissipated by L? W

Explanation / Answer

XL=2pifL=2pi*530*20*10^-3

XL =66.6 ohms

Xc=1/2pifC =1/2pi*530*4.9*10^-6

Xc =61.3 ohms

Z=sqrt[R^2+(XL-Xc)^2] =sqrt[19^2+(66.6-61.3)^2]

Z=19.73 ohms

e)

V =VL-Vc =3.8013*66.6-3.8013*61.3

V=20.147 V

f)

V =75 V

g)

P=I^2*R=3.8013^2*19

P=274.55 W
