Voltage
-
Measured in Volts.
-
It only makes sense to talk about Voltage if it is between 2 points, as it is a Potential Difference ; therefore, there is no "Point Voltage".

Current
-
Measured in Amperes.
-
The question "Does X current shock me?" is a bad question, because current is dynamic and depends on the Total Resistance of the circuit. That is, when connecting to the circuit, the system's Current will decrease depending on the Resistance of the person's body, which depends on the contact surface, total contact area, etc.
