Assignment:
There is a current of 10.0 amperes initially in the long straight wire shown at the bottom of the following diagram produces a flux of 0.0511 webers in the single loop circuit containing the resistor. If the current in the long straight wire is uniformly reduced to ¼ of its original value in 1.99 ms, the flux in the circuit is uniformly reduced to¼ of its value in that same time.
1.) What is the current in the resistor during the 1.99 ms reduction if the resistor value is 330 ohms?
2.) Which terminal of the resistor will be positive, a or b?
