What happens when I run 220v motor on 110v AC?

2019-02-20

There are only two possible results you will observe: 1)The motor doesn’t run at all; 2)The motor will rotate but can’t up to a good state.

If a 100-ohm resistor gives a reading of 30 ohms, can it be used for 30 ohm?

2019-02-20

For the sake of the circuit, you’d better not use it. Why? Obviously, the 100 ohm resistor is broken. In such a case, if you still try to use this broken 100 ohm resistor as a 30 ohms one, which is possible to cause the short circuit eventually.
