ViviTo determine the hours a 3600-watt load will last on a 637 amp battery, you need to convert the wattage to amperes. You can do this by dividing the wattage by the voltage of the battery. Assuming a standard 12-volt battery, 3600 watts divided by 12 volts equals a current of 300 amps. Dividing the battery capacity (637 amp-hours) by the current (300 amps) gives you approximately 2.12 hours of runtime.

How long will a 12 volt battery provide 100 watts?
To calculate the duration a 12 volt battery will provide 100 watts of power, you can use the formula P = V x I, where P is the power (100 watts), V is the voltage (12 volts), and I is the current. Rearranging the formula to solve for current, we get I = P / V. Plugging in the values gives I = 100 watts / 12 volts = 8.33 amps. The battery's capacity, typically measured in ampere-hours (Ah), can then be used to determine how long the battery will last. If the battery capacity is say 50Ah, you can divide the capacity by the current to find how long the battery will last: 50Ah / 8.33A = approximately 6 hours.
How many batteries would it take to light a 12 volt 100 watt light bulb?
To power a 100-watt light bulb with a 12-volt battery, you would need to divide the wattage by the voltage to find the current draw, which is 8.33 amps in this case. Then, depending on the capacity of the battery, you would need to calculate how many hours the bulb can be powered for.
How long would a 12 volt 7 amp hour battery last if converted to 120 volts ac using 20 watts?
Assuming 100% efficiency in the conversion process, the power output would be 7 hours at 12 volts, so the total watt-hours of energy stored in the battery would be 12 volts * 7 amp-hours = 84 watt-hours. With a load of 20 watts, the battery would last 84 watt-hours / 20 watts = 4.2 hours when converted to 120 volts AC.
How can you know my cardiac pacamker remaining time in ampere-hours when all data i have is 2.75 Volts and I know Volts equals Watts divided by Amp?
To calculate the remaining time of your cardiac pacemaker in ampere-hours, you need to know the average current consumption of the pacemaker in amperes. If you have the voltage (2.75V) and the relationship that Volts = Watts/Amps, you also need to know the power consumption in watts to find the current in amperes. Once you have the current consumption in amperes, you can calculate the remaining time by dividing the capacity of the pacemaker's battery in ampere-hours by the current consumption.
How long would an 8 Amp hr battery last with 75mA current draw?
An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.
