Question

Find the current (I) in the following circuit diagram

• A. 5A
• B. 4A
• C. 3A
• D. 2 A

Answer 1

The Correct Option is D

To solve the problem, we need to find the total current flowing in the circuit using Ohm's Law.

1. Identify the Components:
- Two resistors in series: $5\,\Omega$ and $10\,\Omega$
- Voltage source: $30\,V$

2. Calculate the Total Resistance:
Since the resistors are in series, the total resistance $R_{\text{total}}$ is:

$ R_{\text{total}} = 5 + 10 = 15\,\Omega $

3. Apply Ohm's Law:
Ohm's Law: $ I = \frac{V}{R} $

Substitute the values:
$ I = \frac{30}{15} = 2\,A $

Final Answer:
The current in the circuit is $ 2\,A $.
