Ohm's law defines the relationship between the voltage, current, and resistance in an electric circuit: I = V / R. The current is directly proportional to the voltage and inversely proportional to the resistance.
Now you can not decide and specify both the Voltage and the Current both that a subject will be subjected to. There is a source which has a Voltage which comes first and considering that 1 Volt source will not pass a 230 Amp current through you. The actual current will depend on your resistance. Quote.
