When we apply the loop rule (also called "Kirchhoff's loop rule") in electric circuits then when we move through an ideal emf device from positive to negative terminals o a. then the change in the potential is + (emf) o b. then the change in the power is + (current times emf) O c. then the change in the potential is - (emf) o d. then the change in the power is - (current times emf)

Hi, Here's my question. 26.45: An emf source (e=120 V), a resistor (R=80.0 W), and a capacitor (C=4.00 mF) are connected in series. As the capacitor charges, what is the magnitude of the charge on each plate of the capacitor when the current in the resistor is 0.900 A? Hint: From the information given, first calculate the voltage across the capacitor when the 0.900 A current flows in the circuit. Then use the voltage as a function of the time equation for a charging capacitor in an R-C circuit.
Imagine a hypothetical universe where Ohm's law still holds true, but the nature of matter allows for electrical resistors to possess negative resistance values. In such a universe, how would the rules for combining resistors in series and parallel change? Furthermore, how could this altered physics influence the functioning of basic electrical circuits and energy conservation principles?
