- Homework Statement
- The electrical circuit consists of amperemeters. Constant voltage was applied to ´E and F. In the result, one of the amperemeters showed 7 mA and another showed 18 mA. What does the sum of results of all amperemeters equal to?
- Relevant Equations
- $$I_4 = maximim$$
$$I_1 = I_2$$
$$I_3 = I_5$$
$$I_7 = I_ {10} = I_8 = I_6$$
First, I got rid of amperemeters with 0 values. These are 9. 11 and 12.
Amperemeter 4 will show the maximum value of electric current as it is placed directly between E and F. But how to know its value? Will it be 18 mA? I doubt because 18 mA is not said to be the maximum value.
All other amperemeters will show smaller results. Number 1 and 2 will show equal results. Number 5 and 3. And number 7, 10, 8 and 6 as current will not go to the 12-9-11 line and the resistance of wires is neglected. Is it correct?
