Question
if you were to accidentally connect the ammeter paralell tothe resistor rather than in series with it, which device would havemore current flow through it, the meter or the resistor? what wouldhappen to the meter? ok, i know that the meter would have more current flow throughit because it has less resitance than the resitor, but what wouldhappen to the meter? if you were to accidentally connect the ammeter paralell tothe resistor rather than in series with it, which device would havemore current flow through it, the meter or the resistor? what wouldhappen to the meter? ok, i know that the meter would have more current flow throughit because it has less resitance than the resitor, but what wouldhappen to the meter?Explanation / Answer
. You're correct; an ammeter has a very lowinternal resistance and will shunt the majority of the current...for a short period of time. Then it would overheat andphysically melt a small section of the wire carrying the currentwhich would open the ammeter circuit rendering it useless. "Back in the day" of the D'Arsonval meter movement (meterswith a pointer that moves across a graduated scale) placing anammeter in parallel with the circuit would "peg" the pointeragainst the stop until the circuit overheated or blew an internalfuse... yes, the better quality meters were fused because thissometimes happened inadvertently. Today, most digital ammetershave been designed with protection circuits that prevent anoperator from over-loading the meter. .Related Questions
