The correct Answer is:
To solve the problem of calculating the amount of current drawn by an electric pump of 0.8 HP connected to a 220 V power supply, we can follow these steps: ### Step-by-Step Solution: 1. **Convert Horsepower to Watts**: The power of the pump is given in horsepower (HP). We need to convert this to watts (W) using the conversion factor: \[ 1 \text{ HP} = 746 \text{ W} \] Therefore, for 0.8 HP: \[ P = 0.8 \text{ HP} \times 746 \text{ W/HP} = 596.8 \text{ W} \] 2. **Use the Power Formula**: The relationship between power (P), voltage (V), and current (I) is given by the formula: \[ P = V \times I \] Rearranging this formula to find the current (I), we get: \[ I = \frac{P}{V} \] 3. **Substitute the Values**: Now, we substitute the values we have into the formula. We know: - \( P = 596.8 \text{ W} \) - \( V = 220 \text{ V} \) Thus, \[ I = \frac{596.8 \text{ W}}{220 \text{ V}} \] 4. **Calculate the Current**: Performing the calculation: \[ I = \frac{596.8}{220} \approx 2.71 \text{ A} \] ### Final Answer: The amount of current drawn by the electric pump is approximately **2.71 A**. ---
