    How Does Free Electron Density Affect Hall Voltage in a Semiconductor?

    The question is... A Hall probe is constructed from a semi-conducting material of thickness 0.4 millimeters. When 5 amps of current passes through the material a Hall voltage of .6 volts is produced when the probe is placed in a uniform magnetic field of 0.01 Tesla. Assuming the current is...

    How Do Transformers and Resonance Affect AC Circuits?

    A 240 RMS voltage source is connected to a step down transformer with primary windings consisting of 2000 turns or wraps. A secondary set of windings consist of 500 turns or wraps and is connected to an inductor of 0.03 Henry's, a 0.004 farad capacitor and a 120 ohm resistor. Determine the...
