SUMMARY
Real ammeters possess internal resistance, which increases the overall resistance in a circuit, leading to a decrease in current. Conversely, real voltmeters have finite internal resistance, which draws current and consequently lowers the measured potential. Ideal instruments, such as an ideal ammeter and voltmeter, do not exhibit these characteristics; the ideal ammeter has no internal resistance while the ideal voltmeter has infinite internal resistance. Understanding these distinctions is crucial for accurate circuit analysis.
