Question

which statement describes the relationship of voltage and current?
voltage is directly proportional to current because ( i=\frac{v}{r} ).
voltage is inversely proportional to current because ( i=\frac{v}{r} ).
voltage is directly proportional to current because ( i = vr ).
voltage is inversely proportional to current because ( i = vr ).

Explanation:

Ohm's Law states \( I = \frac{V}{R} \), where \( I \) is current, \( V \) is voltage, and \( R \) (resistance) is constant for a given conductor. Rearranging gives \( V = IR \), meaning voltage is directly proportional to current when resistance is fixed. The correct formula is \( I = \frac{V}{R} \), and direct proportionality means as \( V \) increases, \( I \) increases proportionally.

Answer:

Voltage is directly proportional to current because \( I = \frac{V}{R} \)
