In the given circuit, the reading of the ammeter is:
In the given circuit, the reading of the ammeter is:
Show Hint
Kirchhoff's current law states that the sum of currents entering a junction is equal to the sum of currents leaving the junction.

- 6 A
- 4 A
- 2 A
- 1 A
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Using Kirchhoff's current law (KCL), we sum the currents entering and leaving the junction where the ammeter is placed:
\[
I_{\text{ammeter}} = 10A - 6A - 8A + 2A = 6A
\]
Thus, the reading of the ammeter is 6 A.
