What is the effect on a rectifier's current output if the voltage remains constant and the circuit resistance increases?

• A. Increases current output
• B. Decreases current output
• C. No effect on current output
• D. Current output becomes zero

Answer: (B)

When the voltage across a rectifier remains constant and the circuit resistance increases, the current output will decrease. This relationship is explained by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), formulated as I = V/R. In this scenario, since voltage is held constant, an increase in resistance proportionally reduces the current output. This means that as the resistance increases, the denominator of the equation becomes larger, resulting in a smaller value for current. Therefore, if the circuit's resistance increases while the voltage stays the same, the output current will indeed decrease.
