WebApr 11, 2024 · One way to do this problem is to first work out the total current and then use KVL around the loop, adding in the successive resistors as you go. For example, finding the voltage at point C you could start at the negative terminal of the 15 V battery and work your way around the loop clockwise until reaching point C. WebFeb 20, 2024 · Since each resistor in the circuit has the full voltage, the currents flowing through the individual resistors are I1 = V R1, I2 = V R2, and I3 = V R3. Conservation of charge implies that the total current I …
