TY I didn't see that it was semi. =)

I used the equation Torque = NAIB Sin angle N= 8 A= .376 m^2 I = 5.85 B= 2.02 10-4 T for the angle i used 90 degrees

Problem: An eight turn coil encloses an elliptical area having a major axis of 40.0 cm and a minor axis of 30.0 cm. The coil lies in the plane of the screen and has a 5.85 A current flowing clockwise around it. If the coil is in a uniform magnetic field of 2.02 10-4 T directed toward the...

would i then proceed to plug in the variables and solve for I(f)

since the voltage is the same, they would drop out of the equation

I'm not sure which equation for resistance to use

yes that was stated in the problem . I was thinking that this relates to the resistivity since that changes with temperature. There an equation that relates Resistance to resitivity. R = Resistivity (L/A). Not sure if i could go anywhere with that

Homework Statement While taking photographs in Death Valley on a day when the temperature is 59.0°C, Bill Hiker finds that a certain voltage applied to a aluminum wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current...
