Multiple Choice

How many 1250-watt appliances can be used on a 50-amp, 120-volt branch circuit?

Explanation:

Using the formula \( \text{Power (Watts)} = \text{Voltage} \times \text{Current (Amps)} \), we can find the total wattage that a 50-amp circuit can handle at 120 volts: \[ \text{Total Power} = 120 \, \text{volts} \times 50 \, \text{amps} = 6000 \, \text{watts} \] Next, we need to find out how many 1250-watt appliances can be powered by 6000 watts. To do this, divide the total available wattage by the wattage of each appliance: \[ \text{Number of Appliances} = \frac{6000 \, \text{watts}}{1250 \, \text{watts/appliance}} = 4.8 \] Since you cannot have a fraction of an appliance, we round down to the nearest whole number, which is 4. Therefore, 4

    Decent resource, but I'm still studying. Some questions repeat, and I hoped for deeper diagrams on service calculations. The flash cards are helpful though, and I can see progress. If you need a flexible online option, this can be part of your plan, just manage expectations about coverage.
