The potential difference across a coil is 3.08 V at an instant when the current is 305 mA, changing at a rate of 285 mA/s. At a later instant, the potential difference is 1.51 V, while the current is 365 mA, decreasing at a rate of 153 mA/s.
a) What is the inductance of the coil?
b) What is the resistance of the coil?
