Asked by Ethan
Look at the diagram below. The reading on ammeter 1 is 0.15A. What will the reading on ammeter 3 be?

I can't see the diagram you mention — could you upload it or describe the circuit (how the ammeters and resistors/battery are connected and any resistor values)?
Meanwhile here are the common possibilities and how to decide:
- If ammeter 3 is in series with ammeter 1 (same wire, no branching between them) then the current is the same everywhere in that series path, so I3 = I1 = 0.15 A.
- If ammeter 1 measures the total current and that total splits into two equal branches and ammeter 3 is in one branch, the branch currents are half of 0.15 A, so I3 = 0.075 A.
- If the total I1 splits into two branches with resistances R2 and R3, the currents split by the current‑division rule:
I3 = I1 × R_other / (R2 + R3).
(For the branch containing R3, "R_other" = R2.)
If you post the diagram or describe which ammeters are in series or across which resistors and their values, I’ll compute the exact reading for ammeter 3.
