Volts of power? Your question makes no sense. To remove a lug nut use an air impact wrench or a hand wrench and just take it off. Volts has nothing to do with it even if you were using an electric air impact wrench. On an electric air wrench the power of the wrench is measured in torque not volts.
Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps
Watts = Volts x Amps So you need to know the current. This is only for resistive load.
To work this out you will need to know the current that is travelling through the device. You can then find the number of volts by dividing the power (watts) by the current (amps).
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
watts = volts x amps, example-2 watts=2 volts x 1 amp, example- 2 watts=120 volts x .60 amp.
To calculate the number of watts when given volts, you also need to know the current (in amps) flowing through the circuit. The formula for power (in watts) is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Without knowing the current, we cannot determine the number of watts from just volts.
You look at the job you need to do, ie, how many volts and amps, or volts and watts, that you need. Then you look in the catalogs for a solar cell or solar cell array to produce that much power.
You will need to purchase a power inverter. Click the link for one I found.
If you are looking for a power inverter then you are going to need to take a number of things into account. These power inverters are not all equal, and they will vary in price and functionality. This blog will look at how you can narrow down your search to the right power inverter for your needs.
To calculate the voltage, you need to know the current (amperage) as well. The formula to calculate power (watts) given voltage (volts) and current (amps) is: Power (P) = Voltage (V) x Current (I). Without knowing the current, it is not possible to directly convert watts to volts.
You need the formula: Amps * Volts = Watts But you get to do the math.
It depends upon how far you need to take it.
