Formula for finding current
WebI = 30 A, R = 10Ω. Using Current formula. I = V/R. 30 = V/10. V = 30 × 10. V = 300. Hence, Potential difference is 300 V. The potential difference in an electric circuit is 16 V, and the current value is 8 Amp, respectively. Using the current formula, find the resistance of … 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 power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
