Question

L. An electrical engineer increases the voltage in a circuit and measures the resulting current. The results are shown in the table, and the graph shows the data points and corresponding trend line.

Estimate the value of the slope of the trend line, and explain what it means in
this context.
A. The slope is approximately 0.16 and means that the current increases 0.16 ampere for every one-volt increase in voltage.
B.
The slope is approximately 0.16 and means that the current increases 0.16 ampere for every one-volt decrease in voltage.
C.
The slope is approximately 0.8 and means that the current increases from an initial value of 0.8 ampere as voltage increases.
D.
The slope is approximately 0.8 and means that the current increases from an initial value of 0.8 ampere as voltage decreases.

Answer 1

Answer: OPTION (A)

Hence, OPTION (A): The slope is approximately 0.16 and means that the current increases by 0.16 ampere for every one-Volt Increase in voltage

• Explanation:

• Solve the Problem:

SLOPE = Δy / Δx

(30, 4.8 ), (5, 0.8 )

SLOPE = 4.8 - 0.8 / 30 - 5

= 4 / 25

SLOPE = 0.16

• DRAW THE CONCLUSION:

Hence, OPTION (A): The slope is approximately 0.16 which means that the current increases by 0.16 ampere for every one-Volt Increase in voltage.

I hope this helps you!
