Multiple Choice

A kilowatt of power will be drawn from a 500 volt DC supply by a load of?

Explanation:
To determine how much current is drawn from a 500-volt DC supply when a power load of one kilowatt is connected, we use the relationship defined by the power formula: Power (P) in watts is equal to Voltage (V) in volts multiplied by Current (I) in amperes. This relationship can be represented as: P = V × I In this scenario, we need to rearrange the formula to solve for current: I = P / V Substituting the known values into this equation, we can convert one kilowatt to watts (1 kW = 1000 watts). Therefore, we have: I = 1000 watts / 500 volts Performing the calculation gives us: I = 2 amperes This means that a load of one kilowatt will draw 2 amperes of current from a 500-volt supply, confirming that the correct answer is indeed that the load draws 2 amperes. Understanding this calculation is essential for working with electrical systems, where knowing the relationship between power, voltage, and current helps in designing and troubleshooting electrical circuits.
