(b)
Answer to Problem 116P
The current through the ammeter
Explanation of Solution
Consider left top
For ammeter
This resistor is in series with
Substitute the value of
Conclusion:
Substitute
From the previous part the effective resistance right of ammeter
This is the voltage across the ammeter
Then current through ammeter
Therefore, the current through the ammeter
