There is no formula to convert voltage. Voltage is universal.
The formula you are looking for is I = Watts/ Voltage, I = 3000/voltage.
Formula for what?!
Power is voltage times current.
V=ir
Voltage(volts)=Power(watts)/Current (ampheres) Or Voltage=Curren X Resistance(Ohms) -X
Va-Vb
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V

power = current x voltage
Current = voltage/resistance
a=b/5*c
