Q1
In a circuit with two loops, if the current in the first loop is 2 A and in the second loop is 3 A, what is the total current entering a junction where these loops meet?
1 A
5 A
6 A
2 A
According to Kirchhoff's current law, the total current entering a junction equals the total current leaving it. Therefore, total current = 2 A + 3 A = 5 A.

Q
Q: In a circuit with two loops, if the current in the first loop is 2 A and in the second loop is 3 A, what is the total current entering a junction where these loops meet?
Solution: According to Kirchhoff's current law, the total current entering a junction equals the total current leaving it. Therefore, total current = 2 A + 3 A = 5 A.
Steps: 5
Step 1: Identify the currents in each loop. The first loop has a current of 2 A and the second loop has a current of 3 A.
Step 2: Understand that when these loops meet at a junction, the currents combine.
Step 3: Add the currents together: 2 A (from the first loop) + 3 A (from the second loop).
Step 4: Calculate the total current: 2 A + 3 A = 5 A.
Step 5: Conclude that the total current entering the junction is 5 A.
