There are three resistors in a series circuit and each resistor has 2.5 V voltage drop across it. What do you guess about their resistances? all are equal 0 all are different faulty resistors

Solution

Each circuit with R resistance combines and forms a combined Resistance of 3R

Drop of Voltage across each resistance = 2.5V

In a series collection of resistors same current goes thru. Also, 2.5V being the same drop means that Resistance should be same ( V=IR formula)

Hence the answer is A) All are equal
