Q. plan,design and conduct a practical investigation to determine the value of an unknown resistor 2.hand in your draft plan and design prior to conducting your investigation. 3.write a scientific report and hand it in for assessment.
Q. Suppose the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carries the same total current in opposite directions. Determine the magnetic field at a distance R from the axis.
