A 10 V battery is connected to a voltage divider circuit which consists of a 100 Ω resistor and a 300 Ω resistor.
a What is the voltage across the 300 Ω resistor?
A 2.5 V
B 3.3 V
C 7.5 V
D 13.3 V

b) What is the voltage drop across the 100 Ω resistor?
A 2.5 V
B 3.3 V
C 7.5 V
D 13.3 V

a) C. 7.5 V

b) A. 2.5 V

Explanation:

First, we find the total resistance of the circuit. A voltage divider circuit is a series circuit. Therefore, its total resistance will be the sum of individual resistances:

a)

Now, we will apply the voltage divider rule on this circuit to find the voltage across the 300 Ω Resistor (R₂):

V₂ = 7.5 V

Therefore, the correct option is:

C. 7.5 V

b)

Now, the voltage across the 100 Ω Resistor (R₁) will be:

Therefore,the correct option is:

A. 2.5 V

it would be c. predictability
