What can cause high amperage on a motor?
What can cause high amperage on a motor?
Last answer:
High amperage can result in a motor when the amount of load increases. when load increases , it reduces the rotor speed which increases the slip at constant synchronous speed ... , as a result more current shall have been drawn to maintain the additional load.

Why high voltage can reduce power loss?
Why high voltage can reduce power loss?
Last answer:
when voltage has increased due to reduced current flow, thus power loss given by ( I^2R) will be low due to reduced current(I^2) provided that resistance (R) is constant.

What kills, current or voltage?
Last answer:
Current would kill. You can actually have thousands of bolts going through you and not even know it. Yes you probably know already voltage is current times resistance. Since your body is a resistor it would take just a small amount of current to create a very high voltage
