Formula to Convert Volts to Amps
You can calculate amps using these formulas:
1. Using Power:Step-by-Step Example (Using Power)
Example: Voltage = 120V, Power = 600W
Step 1: Identify the formula
Amps = Watts ÷ Volts
Step 2: Insert values
Amps = 600 ÷ 120
Step 3: Calculate
Amps = 5A
Result: The current is 5 amps.
Step-by-Step Example (Using Resistance)
Example: Voltage = 12V, Resistance = 6Ω
Step 1: Use Ohm’s Law
Amps = Volts ÷ Resistance
Step 2: Insert values
Amps = 12 ÷ 6
Step 3: Calculate
Amps = 2A
Result: The current is 2 amps.
