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
