Dangers Of High Voltage: Common Hazards & Safe Practices
Definition of High Voltage. In the realm of electricity, "high voltage" is a relative term, its value largely depends on the context. The International Electrotechnical Commission (IEC) defines high voltage as any voltage over 1000 volts for alternating current (AC) and over 1500 volts for direct current (DC).

Why brushless DC (BLDC) motors usually have low voltage and high ...
A high-voltage wound motor draws less current for the same power output than a motor wound for a lower voltage. Lower current means less heat dissipation in the power wires leading to the motor, so thinner gauge (and therefore lighter) wiring can be used. In this way a high-voltage electrical system in an aircraft saves on weight.

High Current or High Voltage that damages components?
1) For example if you have a working circuit with a 10V battery, fixed 5 Ohms resistance and a current of 2A. If you then swap that battery to 20V, would it be the new current of 4A that does the damage or that fact that the voltage is now 20V? Both values are higher than they should be so which factor will do the damage, both?
