A: By saturating a transistor meaning forward bias the base to emitter the voltage across the collector and base should be very low . depending on current it can be .050 v to .5v reversing or removing the bias voltage this voltage should be the same as the rail
For a normal transistor, it would probably be around 2 volts or so. I'd use 5 volts, just to be sure.
You need the formula: Amps * Volts = Watts But you get to do the math.
You need to have the amperage to determine how many volts you get out of 20 watts.
15.
Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
Look on the devices nameplate. There it should have the wattage, volts, and amperage.
If you need to jump start the car then the battery may be fully charged but it is defective and needs replacing. A full charged battery will read 12.6 volts at the posts with the engine not running. 12 volts indicates the battery is only 25% charged.
Most batteries today are sealed so a hydrometer is useless. A fully charged battery will read 12.6 volts with a digital volt meter. At 75% charge it will read 12.4 volts, at 50% it will read 12.2 volts and at 25% charge it will read 12 volts. But if you have another type battery then here is what you need to know. A fully charged golf cart battery or fork lift battery will read 1300 A fully charged auto or truck battery will read 1275 A fully charge cell phone tower or solar storage battery will read 1250

Assuming the car's electrical system is 12 volts, the answer is 12 volts??
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
You need to divide the 48 volts by the voltage produced by a single battery.
10 volts minimum,18 max.
No volts need a hard drive. However hard drives need a voltage. Usually about 5 for the data more for the physical movement of the drive.

You will need a little more than 9 volts to kill a mosquito. It is recommended that you use about 2850 mAh of current to kill a mosquito.
How many volts woud it take to charge a laptop
