    Who Can Crack the R-L-C Circuit Challenge?

    Can anyone solve this? I've asked 3 professors! I'm having trouble trying to understand this problem. The R-L-C series circuit is driven with a AC source with EMF=Vo*sin(wt) where Vo=110.0V and f=60.0 Hz. If R = 20.0 Ohms, L=5.0 * 10^-2 H, and C=50.0uF, find the potential drops across the...

    What Causes Voltage Drops Across an Inductor in an R-L-C Series Circuit?

    Trouble with the R-L-C series. Please Help! I'm having trouble trying to understand this problem. The R-L-C series circuit is driven with a AC source with EMF=Vo*sin(wt) where Vo=110.0V and f=60.0 Hz. If R = 20.0 Ohms, L=5.0 * 10^-2 H, and C=50.0uF, find the potential drops across the...

    Calculating Induced EMF in a Conducting Loop with Changing Magnetic Field

    Here is a bonus question that I was given yesterday. I am completely at a loss of what to do. Any suggestions? A conducting loop with a half circle of radius r=0.20m and 3 straight sections. The half circle lies in a uniform field B that is directed out of the page. The magnitude of B as a...
