Answer:
Explanation:
IR drop across resistor means there is a change in potential or voltage across the resistor due to current flowing through the resistor. According to ohm's law
V = RI
where, V = voltage across the resistor
R = resistance
I = current
Now,we know R is constant. And for particular resistance, current depends on applied voltage. So, when current passes through a resistor, no change in current seen unless we change the resistance.
