Webthe current has only one path to take – the current is the same through each resistor. The sum of the potential differences across each resistor equals the total potential difference across the whole chain. The I’s are the same, and we can generalize to any number of resistors, so the equivalent resistance of resistors in series is: VVV=+12 WebOhm's law calculation formula. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): I =. V R. Example. I =. 20V 10Ω. = 2A. The … WebFeb 9, 2024 · First we must compute the current through each bulb, using Ohm’s law: Substituting V ¼ 120 V and R1 ¼ 240 V into V = I x R, we obtain I 1 = 0.5 A. For R 2 = 480 V, we get I 2 = 0.25 A. Now we can use these values for I and R in the power formula, P = I 2 x R, which yields P 1 = (0.5 A) 2 x 240 V = 60 W and P 2 = (0.25 A) 2 x 480 V = 30 W. scarborough college sports calendar
