how would the ammeter resistance affect the total current when the instrument is inserted in the circuit to measure the current? does this give you an idea about the desirable design of ammeters? why?...thanks for helping :smile:

Do you place the ammeter in parallel or series to the current you are measuring? How do you measure total resistance for such a circuit with the ammeter present? How does resistance affect current?
