Consider the following electrical circuit diagram in which nine identical resistors of 3 Ω each are connected as shown. If the reading of the ammeter A1 is 1 ampere, answer the following questions :
(a) What is the relationship between the readings of A1 and A3 ? Give reasons for your answer.
(b) What is the relationship between the readings of A2 and A3 ?
(c) Determine the reading of the voltmeter V1.
Solution
(a) Both have same reading / A1 = A3
Both are connected in series
(b) Reading of A2 = 1/4 A as current is equally divided in the four identical resitors. /Reading of A2 = 1/4 times Reading of A3. / A2 =0.25 A / A2
