Multiply the voltage by the current, so 240 x 5 and the answer is in watts (for some types of equipment there is also a power factor).
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
To calculate the watt-hours of a 200Ah battery at 12V, you can use the formula: Watts = Volts × Amperes. Therefore, a 200Ah battery at 12V would provide 2400 watt-hours (Wh) of energy (200Ah × 12V = 2400Wh). This means the battery can theoretically supply 2400 watts for one hour, or proportionally less for a longer duration.
As watts equals volts times amps (ohms law simplified) you are missing part of the equation.. Let's say you are asking about how many watts is 1 amps at 12v then... If W = V x A then 1A at 12v = 12 watts
You need to know the volts of the device to answer the question, if it's a household appliance (120v) then the answer is 36 watts, if it's an automobile device (12v) then the answer is 3.6 watts
In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
A typical 12V starter motor for a car can range from 500 to 2,000 watts, depending on the size and design of the motor.
12 V DC, 18 VA (watts) how many amps? Formula: amperage I = power P (VA) divided by voltage V. So, amperage I = 18 watts / 12 volts = 0.083 amperes.
Approximately ten amps available at the lighter's socket. Ohm's Law thus gives 12V x 10A = 120 Watts...
The power (in watts) can be calculated by multiplying the current (in amps) by the voltage (in volts). In this case, 10 amps at 12 volts would result in 120 watts of power (10A * 12V = 120W).
well the equation for amps is a= watts/volts so 25/12= 2.0833333333amps
what do you mean by 5? an inverter just steps a voltage up from a lower voltage( i assume you are talking about a 12v to 240v inverter) 1:20 ratio. so with 100Ah at 12v you should get 240v at 5amps for 1 hour more batteries in parallel will increase this figure.
