Question

A scientist conducted experiments and recorded measurements of battery voltage and current flowing through the battery. They then produced the model shown below.

Based on the data provided in the graphical model, predict the current that would flow through a circuit, similar to the ones studied, that is powered by a battery with a voltage of 15 V. Support your prediction with evidence and reasoning.
a) 2 A
b) 4 A
c) 6 A
d) 8 A

Answer 1

Based on the provided graphical model, a battery voltage of 15V would correspond to a current of approximately 6A.

Step-by-step explanation:

To predict the current that would flow through a circuit powered by a 15V battery, we can refer to the graphical model provided. The graph shows a linear relationship between voltage and current, where the current increases by a constant amount for each increase in voltage. To find the current at 15V, we need to find the corresponding point on the graph. From the graph, it appears that a voltage of 15V would correspond to a current of approximately 6A. Therefore, the predicted current would be 6 A. which can occur due to wear or manufacturing inconsistencies. If the measurements taken at opposite ends vary, it indicates the presence of taper, which affects how the bearing will fit and function around the crankshaft.
