In a simple circuit with a fixed applied voltage $V$, how does increasing the resistance $R$ affect the electric current $I$ according to Ohm’s law?

• A. The current stays the same because current is independent of resistance when voltage is fixed.
• B. The current decreases because $I=\frac{V}{R}$, so increasing $R$ makes $I$ smaller.
• C. The current becomes zero for any increase in $R$, because any resistance blocks all current.
• D. The current increases because $I=\frac{R}{V}$, so increasing $R$ makes $I$ larger.

Answer: (B)
