When a resistor is connected across the terminals of an acgenerator (104 V) that has a fixed frequency, there is a current of 0.505 Ain the resistor. When an inductor is connected across the terminalsof this same generator, there is a current of 0.384 A in the inductor. When both the resistor andthe inductor are connected in series between the terminals of thisgenerator, calculate the following.
a) the impedance of the series combinationb) the phase angle between the current and the voltage of the generator
Two long, parallel conductors carry currents I1 = 3.00 A and I2 = 2.50 A, both directed into the plane of the computer screen. Determine the magnitude and direction of the resultant magnetic field at P.
A flat circular coil with 125 turns, a radius of 3.42 x10-2 m, and a resistance of 0.448 Ω is exposed toan external magnetic field that is directed perpendicular to the plane of the coil. The magnitude of the external magnetic field ischanging at a..
