WebThe voltage coil provides an excitation signal and induces a potential E on the circuit under test. Under the action of the potential E, the circuit under test produces a current I. The clamp meter measures E and I, and the measured resistance … WebA coil is connected in series with a 11.2 k Ω resistor. An ideal 72.1 V battery is applied across the two devices, and the current reaches a value of 1.75 mA after 4.42 ms. (a) Find the inductance of the coil. (b) How much energy is stored in the coil at this same moment? (a) Number Units (b) Number Units
