I don't see a question. Please clarify if you want an answer.
No. Only less.
If you had 12 volts across 2000 ohms, you would get 6 milliamperes, not 70 amperes. Ohm's Law: Voltage = Current times resistance. This situation is impossible per ohms law: E = I x R In order to push 70A through a 2000 ohm reisistor requires 140,000 Volts! In order to get 70A from a 12V supply a 0.171 ohm (171 milli-ohm) resistor is required. 70A @ 12 V is 840 Watts 70A through 2000 ohms is 9.8 Megawatts!! (P = I^2 x R)</P>
"2kw fire" if this refers to an electric fireplace then you also need to know the voltage that is used. 1Kw = 1000 watts. Watts = Amps x Volts. Amps = Watts/ Volts. Amps = 2000/Volts.
I=U/R so 30/2000=0.015 so 15 mA
25*80 = 2000 JOULES
Hi, The normal voltage to have the vehicule to properly operate has to be a minimum of 12.6 volts. When checking the voltage at the battery when the engine is running, except to have about 14.4-14.6 volts.
To calculate the amperage, you would need to know the voltage of the system. If you assume a standard voltage of 120V, you can calculate the amperage by dividing the wattage by the voltage: 2000 watts / 120 volts = 16.67 amps.
The pump runs on 12 volts.
12 volts.
Your alternator should be producing between 13.9 and 14.3 volts.
If you are checking Alternator voltage, It should 12.8 volts to 14.3 with engine running. Battery voltage is 12.3---12.8 with engine off.
Should be around 13.5-15.5 volts.
12 volts.
Your car should be charging at around 14 volts. I would suspect the voltage regulator is at fault if it is charging too high. You can replace the alternator. If you can find an aftermarket voltage regulator you can replace just that. It is on the back of the alternator.
No. Only less.
As of 2000, Australian power points supply AC 230v at 50hz. Pre-2000, it was 240v at 50hz.
