Correct option is D
The correct answer is option (d) Directly proportional to resistance.
Information booster :
The voltage across each resistor in a series combination depends on its resistance, and the total voltage is distributed proportionally to their resistances.
Current is the Same Across All Resistors:
In a series circuit, the same current flows through all the resistors because there is only one path for the current.Voltage is Divided Proportionally:
The total voltage supplied to the series circuit is distributed across the resistors in proportion to their resistances. A resistor with a higher resistance will have a larger share of the voltage drop.
