Wattage is simply voltage x amperage. It's the law. Watt's Law.
Watts are a measure of energy, just different units than calories or BTU.
Voltage is a measure of difference in _potential_, and amperage is a measure of current being moved. So electrical energy depends on a bit of both.
Beyond a certain voltage, it can be somewhat shocking. High enough and it can jump out at you.
And it can be badly damaging.
Also depends on how conductive you are at the time, conductance is the opposite of resistance.
Also depends on how much amperage is available from the source, if the source is fused for 1 amp maximum it would be less risky than higher amperage fuses.
Like with household wiring, if you get shocked and are conductive enough for significant amperage to be passed through your body, the total wattage could be enough of a fraction of a space heater's dissipation to roast the tissues which are involved with conducting the current.
Simply because there's enough amperage available at that voltage to get a space heater red hot, and the circuit breaker will not trip unless you are conducting more than that.
OTOH, sensitive organs can be upset by much lower amperage if it passes along lines where the organs are nearby.
For instance if you work on an electrical box and take a shock from your right hand to your right elbow, it's mainly going to hurt that one arm.
But contact the same two points, one to each elbow, and the heart is at risk much more than before, since the current has to pass through your torso to complete the circuit.
> Watts are a measure of energy, just different units than calories or BTU.
Sorry to be pedantic, but watts are a unit of power, not energy. Power is energy divided by time. The unit of energy is a joule (or, more commonly in household terms, a Watt-hour).
