This photo is an electrical basics chart about Ohm’s Law, showing how to calculate Voltage (V), Current (I), Resistance (R), and Power (P). 1. Ohm’s Law The main formula is: R = V ÷ I Where: R = Resistance, measured in Ohms (Ω) V = Voltage, measured in Volts (V) I = Current, measured in Amperes (A) Example: If voltage = 230 V and current = 10 A: R = 230 ÷ 10 = 23 Ω So the resistance is 23 ohms. 2. To Calculate Current I = V ÷ R Example: If V = 230 V and R = 46 Ω: I = 230 ÷ 46 = 5 A 3. To Calcula
