If you multiply amp by ohm the answers will be in units of?

If you multiply amperes (amps) by ohms, the result will be in units of volts. This follows from Ohm's Law, which states that voltage (V) is equal to current (I, in amps) multiplied by resistance (R, in ohms): V = I × R. Thus, the unit of measurement for the product of amps and ohms is volts.
