The circuit diagram below shows a 9.0 V battery in a circuit with three resistor labeled 1, 2 and 3. What is the voltage drop across resistor :
A
3.0 V
B
9.0 V
C
27.0 V
D
81.0 V
E

Correct option is B)
All the three resistors are connected in parallel with each other as well as the battery, thus voltage drop across each resistor is equal to the voltage of the battery i.e 9.0 V
