The Mystery Circuit

Consider this circuit

*Assume that voltmeter have infinite resistance and ammeter have very low resistance (negligible)

In the following circuit, determine the reading in all the ammeters in the following scenarios,

A.Switches S1 and S2 are open. (Group 1)
B.Switch S1 is closed and switch S2 is opened. (Group2)
C.Switch S1 is open and switch S2 is closed.(Group 3)
D.Switches S1 and S2 are closed.(Group 4)

Task : Each group to provide the following
Time for this task : 15mins

Groups of 4

1.Post on the blog / board the circuit diagram (according to your scenario)
Include the direction of the current flow.
Detail calculation on the following:
Ammeters readings (A1,A2)

2.Ms Teo will handpick the presenter from each group.
Role of presenter to explain the circuit and how all readings are calculated.
