One way to look at this (getting shocked thing), is to relate the Wattage delivered to a Human's Body during a shock scenario.

If, for example, a Person receives a painful shock from an AC Power source, at a Voltage of 120 VAC, and the Current that flows through this Person is 6 ma (Milliamps), the resultant Wattage falls well below 1 Watt (0.72 Watts).

The same 6 ma at 240 VAC will result in a True Power draw of 1.44 Watts, and at 277 VAC, the draw is 1.662 Watts.

In this scenario, the Voltage, Resistance and Wattage change, but the Amperage remains the same value.

A drammatic rise in True Power drawn as the Voltage increases.
Looking at it the other way, there is a drammatic drop in True Power drawn as the Voltage decreases.

This would be results from something having a "User Changable" level of Resistance, which the Resistance may be increased, or decreased, in value in order to connect to a different Voltage level - and still draw the same 6 ma.
Definitely not going to be the results of a Fixed Resistance level, which is somewhat typical for People.

Scenario with a fixed Resistance value will result in large increases in Wattage being delivered, along with increased Amperage, as Voltage increases.

Same values from the AC power source - 6 ma flows when the Person gets connected to a 120 VAC power supply.
This equates to a Resistance of 20 K (20,000 Ohms), and the resultant True Power drawn from the supply is 0.72 Watts.

The same 20 K load (fixed Resistance) connected across a 240 VAC supply results in a 12 ma flow, and a corresponding 2.88 Watts drawn from the Supply.

As you can see, doubling the Voltage resulted in the Wattage drawn being 4 times larger.
Lowering the Voltage by ½ reduces the drawn Wattage to ¼ of that value.

In this scenario, the Voltage, Amperage and Wattage change - but the Resistance remains the same value.

Apply this to any Circuit, any Power Source, at any point on the Source, and get the same results.
