For the circuit in the figure, assume that $ = 14.0 V, R = 7.50 0, and L = 6.20 H. The ideal battery is connected at time t = 0. (a) How much energy is delivered by the battery in the first 3.00 s? (b) How much of this energy is stored in the magnetic field of the inductor? (c) How much of this energy is dissipated in the resistor? Www R (a) Number Units (b) Number Units (c) Number i UnitsA coil with 113 turns has a magnetic flux of 50.3 nT-m through each turn when the current is 3.63 mA. (a) What is the inductance of the coil? What are the (b) inductance and (c) flux through each turn when the current is increased to 7.86 mA? (d) What is the maximum emf E across the coil when the current through it is given by i = (5.75 mA)cos(wt), where w = 72.9 rad/s? (a) Number i Units (b) Number Units (c) Number i Units (d) Number i Units
