4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
If the voltage is AC a transformer can be used.
A "C" battery has a 1.5 Volts same with AAA, AA, and D batteries.
The star point or wye voltage of a 480 volt three phase four wire system is 277 volts. The 480 voltage is divided by the sq root of 3 (for 3 phases). The sq root of 3 is 1.73. 480 volts/1.73 = 277 volts. The same formula is used on all three phase four wire systems. 208 volts /1.73 = 120 volts, 416 volts /1.73 = 240 volts, 600 volts / 1.73 = 347 volts.
It honestly depends on the type of flash light.
There will be a significant reduction in the mechanical power output available from the motor.
volts abbr (V)
There are 1.2 kilovolts in 1200 volts. This is because 1 kilovolt is equal to 1000 volts, so 1200 volts is equivalent to 1.2 kilovolts.
You're trying to convert mechanical force to voltage, and that doesn't work the way you think it does. The voltage doesn't change on account of the truck's horsepower - that's the alternator and voltage regulator which supplies electrical current.
150 volts is 125% of 120 volts.
5000 volts
45 volts
12 volts
The potential difference of 120 volts and 12 volts is 108 volts.
Volts. 12.6 volts = Full Charge 12.4 volts = 75% Charge 12.2 volts = 50% Charge 12.2 volts = 25% Charge
12.6 volts = 100% Charge 12.4 volts = 75% 12.2 volts = 50% 12.0 volts = 00%
