The maximum AC voltage is 50 V and it oscillates at 10 Hertz. Determine the impedance of the circuit. Determine the current in the circuit. Determine what the frequency would need to be for the current to be maximized. 2. Consider a rectangular wire coil that is 50 cm wide by 15 cm tall. There are ten loops in the coil. Notice the 20 resistor in the bottom section of the coil. The rectangular loop is pulled apart by the sides so that it stretches into a very thin loop in 3 seconds as shown below. There is a 4 T magnetic field pointed out of the page. 50CM 15cm Determine the current magnitude induced in the resistor. Determine the direction of the current through the resistor shown. 3. Consider three long wires perpendicular to this page. The first has a current of 20 Amps out of the page. The second which is 2 meters from the first has a current of 15 Amps out of the page. The third which is 5 meters from the first has a current of 10 Amps into the page. Determine the net force per unit length on the 15 Amp wire. 4. A ray of light in water is travelling parallel to the base of a glass tank. The tank has a 50° angle with the horizon. The index of light in air is 1.00, in water is 1.33, and in glass is 1.50. glass wote Light 152 SU Determine the angle of the ray reflected off of the water glass interface.
