Final answer:
A circuit with a 24V voltage source supplying power to a resistance designed for the same voltage will ensure that the load operates at its design power rating, according to Ohm's law and the power formula.
Step-by-step explanation:
The type of circuit that will allow a load to deliver its design power rating if the load is designed for 24V is one where the voltage source perfectly matches the design voltage of the load. For instance, if we have a resistor (the load) that is meant to operate at 24V, then supplying it with a 24V source will ensure that the load operates at its optimal performance level. Using Ohm's law, which states V = IR, we can determine the current required for the load to perform at its design power level by dividing the power (in watts) by the voltage (in volts).
If the load is designed for a specific power rating at 24V, we will need to ensure that the current supplied to it allows for that power to be reached (P = IV), where P is power in watts, I is current in amperes, and V is the voltage in volts. Therefore, a circuit that has a 24V voltage source supplying power to a resistance designed for that same voltage will enable the load to achieve its designated power output.
