    Hi
    Have a 12v battery and a 18V motor and want the motor to run at 18
    I know they use capacitors to up the voltage or putting 2 resistors in parallel
    And I know they use ohms law to work it out
    But I dont understand ohms law so is they any chance please someone could tell me the value of resistor or capacitor I need

    Thanks

    You cannot to this with resistors and capacitors in a DC circuit.
    You need to use a boost converter or a charge pump.
