I read at the power outlet,the meter detect 220 volts but the split type AC doesn't work.it happens when I used the back up generator.

Yes, it is possible for a circuit to have 220 volts but low current. The voltage of a circuit refers to the potential difference between two points, while the current refers to the flow of electric charge. These two are independent of each other and can vary in a circuit.
The voltage of a circuit is important because it determines the amount of potential energy available to move electric charges. This potential energy is necessary for electrical devices to function properly.
No, a circuit with low current is not likely to cause damage. Current is the measure of the rate of flow of electric charge, and low current means there is less charge flowing per unit time. However, it is always important to follow safety precautions when working with electricity.
The current in a circuit can be affected by the resistance of the circuit components, the voltage applied, and the type of material the circuit is made of. Other factors such as temperature, length of the circuit, and presence of external magnetic fields can also impact the current.
To increase the current in a circuit with 220 volts, you can either decrease the resistance in the circuit or increase the voltage applied. This will allow for more electric charges to flow through the circuit, resulting in a higher current.
