According to Ohm's law, how do you calculate amperage?

Multiply volts by resistance
Subtract resistance from volts
Divide volts by resistance
Add resistance to volts

The correct answer is: Divide volts by resistance

Ohm's Law is a fundamental principle that relates voltage, current (amperage), and resistance in electrical circuits. The law is usually expressed in the formula: Voltage (V) = Current (I) x Resistance (R). To rearrange this formula to find the current (amperage), you divide the voltage by the resistance. This means that to calculate the amperage, you take the voltage across the circuit and divide it by the total resistance in that circuit. This relationship is crucial for RV technicians as it helps them understand how electrical systems operate, allowing for effective troubleshooting and repairs. Understanding this formula ensures that technicians can manage power demands in recreational vehicles and maintain safe operational levels to prevent overloads or damage to electrical components.
