Answer:

8.85 hp

Step-by-step explanation:

1. The first thing we need to do is determine our knowns.

Knowns

  • Current = I = 30 Amps
  • Voltage = V = 220 Volts
  • Power = 1 hp =745.7 Watts = ? (What we're looking for)

2. The equation we need to use is one that relates Current, Voltage, and Power to one another.

Power = Current × Voltage

P = IV

3. Plug in all knowns to the equation and solve for Power.

P = 30 A × 220 V = 6600 Watts (or W)

4. Finally, we need to convert Watts to Horsepower.

1 hp = 745.7 W

6600 W × (1 hp / 745.7 W) = 8.85 hp
