Question

In the following figure current I equal to

• A. \(1.1\ \text{A}\)
• B. \(2.2\ \text{A}\)
• C. \(3.3\ \text{A}\)
• D. \(4.4\ \text{A}\)

Hint:

Add the currents entering the junction and subtract those leaving it; the net must be zero.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Kirchhoff's current law: the total current entering a junction equals the total current leaving it.

Step 2: Calculation
Treat the connected wiring in the figure as one node. Add the currents flowing in, subtract the currents flowing out, and solve for \(I\).

Step 3: Compare the options
This gives \(I=3.3\ \text{A}\), which is the third option.

Final Answer:
The current \(I\) is \(3.3\ \text{A}\). \[ \boxed{\text{(C) }3.3\ \text{A}} \]
