Question

How much ampere is in 1.5 ton AC?

Answer 1

To calculate the current (in amperes) for a 1.5-ton air conditioner (AC), you need to know its power consumption (in watts) and the voltage.

### 1. **Convert Ton to BTU:**
1 ton of cooling is equal to 12,000 BTU/hr. So, for a 1.5-ton AC:

\[
1.5 \text{ tons} \times 12,000 \text{ BTU/hr} = 18,000 \text{ BTU/hr}
\]

### 2. **Convert BTU/hr to Watts:**
1 BTU/hr is approximately equal to 0.29307107 watts. So:

\[
18,000 \text{ BTU/hr} \times 0.293 = 5,274 \text{ watts}
\]

### 3. **Calculate Current (Amps):**
To calculate the current, use the formula:

\[
I = \frac{P}{V}
\]

Where:
- \(I\) is the current in amperes
- \(P\) is the power in watts
- \(V\) is the voltage (typically 220V for most ACs in many countries)

So, assuming a 220V supply:

\[
I = \frac{5,274}{220} \approx 24 \text{ amps}
\]

### Conclusion:
A 1.5-ton AC typically draws around **24 amps** under normal operation, though this can vary based on the efficiency of the unit and other factors like startup current and power factor.
