WebA coil of inductance 150 mH and resistance 38 ohms is connected in series with a 14 ohm resistor and a variable capacitor. The combination is connected across a voltage supply … WebThe circuit shown in the figure contains two batteries, each with an emf and an internal resistance, and two resistors. I need to find the magnitude of the current in this circuit. I believe I'm supposed to be using the equation: I = E ( R + r) where E = 24.0 V, R = 17 Ω. So how do I identify the internal resistance. homework-and-exercises
