A circuit contains two resistors connected in parallel. The value of [tex]R_1[/tex] is [tex]30 \Omega[/tex], and the value of [tex]R_2[/tex] is [tex]60 \Omega[/tex]. The supply voltage is 24 VDC. What is the voltage drop across [tex]R_2[/tex]?

A. 12 V
B. 16 V
C. 20 V
D. 24 V



Answer :

To solve for the voltage drop across the resistor [tex]\( R_2 \)[/tex] in a parallel circuit, it's important to understand how voltage behaves in parallel circuits.

Step-by-Step Solution:

1. Understand Parallel Circuits:
In a parallel circuit, the voltage across each component (resistor, in this case) is the same.

2. Given Information:
- Resistor values: [tex]\( R_1 = 30 \Omega \)[/tex] and [tex]\( R_2 = 60 \Omega \)[/tex]
- Supply voltage ([tex]\( V_{\text{supply}} \)[/tex]): 24 V

3. Voltage Drop Across [tex]\( R_2 \)[/tex]:
Since [tex]\( R_1 \)[/tex] and [tex]\( R_2 \)[/tex] are in parallel, the voltage drop across [tex]\( R_2 \)[/tex] is the same as the supply voltage.

Calculation:
- Voltage across [tex]\( R_2 \)[/tex]: [tex]\( V_{R_2} = V_{\text{supply}} \)[/tex]
- [tex]\( V_{R_2} = 24 \)[/tex] V

Therefore, the voltage drop across [tex]\( R_2 \)[/tex] is:

[tex]\[ \boxed{24 \text{ V}} \][/tex]

The correct answer is [tex]\( \boxed{24 \text{ V}} \)[/tex].
