How mane volt 1 oham?

The term "1 ohm" refers to electrical resistance, not voltage. According to Ohm's Law, voltage (V) is the product of current (I) in amperes and resistance (R) in ohms, expressed as V = I × R. Therefore, to determine the voltage across a 1-ohm resistor, you need to know the current flowing through it. For example, if 1 ampere of current flows through a 1-ohm resistor, the voltage would be 1 volt.
