Does 15 amps equals 1500 joules?

Answer 1

No, 15 amps does not equal 1500 joules. Amperes (amps) measure electric current, while joules measure energy. To relate them, you need to know the voltage (in volts) and the time (in seconds) for which the current flows. The formula for electrical energy is ( \text{Energy (Joules)} = \text{Power (Watts)} \times \text{Time (seconds)} ), where power is calculated as ( \text{Voltage (Volts)} \times \text{Current (Amps)} ).
