Chapter 34, Problem 27A

The bulbs shown below are identical. An ammeter is placed in different branches, as shown. Rank the current readings in the ammeter from greatest to least.

To determine

To Rank: The current readings from greatest to least.

Answer to Problem 27A

  $\text{A = B = C}$

Explanation of Solution

Introduction:

An ammeter is used to measure the amount of current flowing through a circuit.

The ammeter is placed in different branches. The bulbs are identical and have same potential difference across it which means same amount of current would flow through it. The current readings of all the three ammeters would be same.

Conclusion:

The rank of current readings from greatest to least:

  $\text{A = B = C}$
