technician a says that when resistance increases, current flow decreases. technician b says that when voltage decreases, current increases. who is correct?\no a. technician a\no b. technician b\no c. both technician a and technician b\no d. neither technician a nor technician b
Answer
Answer:
A. Technician A
Explanation:
Step1: Recall Ohm's Law
$I = \frac{V}{R}$, where $I$ is current, $V$ is voltage and $R$ is resistance.
Step2: Analyze Technician A's statement
When $V$ is constant, if $R$ increases, according to $I=\frac{V}{R}$, $I$ decreases. So Technician A is correct.
Step3: Analyze Technician B's statement
From $I = \frac{V}{R}$, when $R$ is constant, if $V$ decreases, $I$ decreases, not increases. So Technician B is wrong.
