it would depend upon the current. Power (watts) = I (current in amps) x E (voltage).
2 watts = 15 amps x .133 volts
2 watts = 20 amps x .10 volt
45 volts
1000
230 Volts
Zero volts.
1.55 volts
230 volts
45 volts
0.016 volt
4160 volts
50,000 Volts.
900,000 Volts. That is Nine Hundred Thousand volts.
neither...it should have 14.63 volts
