which statement describes the relationship of voltage and current?\no voltage is directly proportional to current because (i = \frac{v}{r}).\no voltage is inversely proportional to current because (i = \frac{v}{r}).\no voltage is directly proportional to current because (i = vr).\no voltage is inversely proportional to current because (i = vr).
Answer
Explanation:
Step1: Recall Ohm's Law
Ohm's Law is given by $I=\frac{V}{R}$, where $I$ is current, $V$ is voltage and $R$ is resistance.
Step2: Analyze proportionality
Rearranging Ohm's Law for $V$ gives $V = IR$. When resistance $R$ is constant, if $I$ increases, $V$ increases and if $I$ decreases, $V$ decreases. So voltage $V$ is directly proportional to current $I$.
Answer:
Voltage is directly proportional to current because $I=\frac{V}{R}$.
