Does higher amperage mean more power?
Furthermore, does higher amps mean more power?
Amps. So amps measures or indicates the maximum time a tool can continuously run without exceeding the temperature limits. Amps basically measure how effectively the motor cools itself, not how much power it has. With this in mind, more amps can be good because motors will run longer and won't heat up as fast.
Also, what happens if amperage is too high?
Voltage: When trying to match a supply to a device, you need to get the voltage right if the supply voltage is too high, then it will damage your device. If the supply voltage is too low, then your device just won't work. If the voltage is too high for the device. If the amps are too low for the device.
While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and 200 mA (0.1 to 0.2 amp) are lethal.
