Final Answer:
The voltage versus current curve for the load R7 in the circuit would exhibit a linear relationship.
Step-by-step explanation:
In this circuit configuration, the load resistor R7 experiences a linear relationship between voltage and current based on Ohm's Law (V = IR). As the load's resistance changes, the voltage across it is directly proportional to the current passing through.
This adherence to Ohm's Law results in a linear graph, where an increase in voltage corresponds to a proportional increase in current and vice versa. This pattern signifies a linear relationship between voltage and current for the load R7 in the circuit.
The linear relationship in the voltage versus current graph for R7 implies that its behavior complies with Ohm's Law, where the resistance remains constant irrespective of the voltage or current applied. This characteristic signifies a straightforward and predictable behavior for the load within the circuit, presenting a consistent ratio between voltage and current.
Here is complete question;
