    I have a question on my assignment for school on ammeters. Wondering if anyone can answer it. What is the measurement of the voltage drop across an ammeter? Thanks

    Do you mean how to determine the in circuit drop across the ammeter?

    Then using a basic Ampere meters. You introduce a small resistor in the loop and measure the voltage drop over this resistor. It is no standard answer as this resistor may depend on manufacture and current magnitude. If you know the current and the resistance you will find the voltage drop

    In a practical ammeter, the voltage drop is determined by the meter shunt value and Ohm's law.
