The information provided is not sufficient to determine the exact amperage of a 1.5-ton inverter 3-star AC. The amperage of an air conditioner depends on several factors, including the voltage rating and the power consumption of the unit.
Typically, the power consumption of an air conditioner is measured in watts. To calculate the amperage, you need to know the voltage at which the AC operates. The formula to calculate amperage is:
Amperage (A) = Power (W) / Voltage (V)
For example, if the power consumption of the AC is 1500 watts and it operates at 220 volts:
Amperage = 1500 W / 220 V ≈ 6.82 A
However, to accurately determine the amperage of a specific 1.5-ton inverter 3-star AC model, you need to refer to the manufacturer's specifications or user manual, as different models can have different power ratings and efficiency levels.
