    Based on Ohm's law, the relation between the current, voltage and resistance can be described using the following equation:

    Voltage = Current * Resistance

    We are given that:

    Current = 25 amperes

    Resistance = 14 ohms

    Substitute with the givens in the above equation to get the voltage as follows:

    Voltage = 25 * 14 = 350 volts
