Aconventional current of 7 a runs clockwise in a circular loop of wire in the xy plane, with center at the origin and with radius 0.097 m. another circular loop of wire lies in the same plane, with its center at the origin and with radius 0.03 m. how much conventional current must run counterclockwise in this smaller loop in order for the magnetic field at the origin to be zero?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
