Question

question 3 of 10
why did you test the resistance of the wire?
a. the current flowing through the lightbulb was too high. increasing resistance would decrease current.
b. the current flowing through the lightbulb was too high. decreasing resistance would decrease current.
c. the current flowing through the lightbulb was too low. decreasing resistance would increase current.
d. the current flowing through the lightbulb was too low. increasing resistance would increase current.

Explanation:

According to Ohm's law $V = IR$ (where $V$ is voltage, $I$ is current, and $R$ is resistance), when voltage is constant, current and resistance are inversely - proportional. If the current through the light - bulb is too high, increasing the resistance will decrease the current.

Answer:

A. The current flowing through the lightbulb was too high. Increasing resistance would decrease current.
