Quick question on connecting ammeter, voltmeter

  1. Jul 21, 2010 #1
    first if i were to connect an ammeter i would connect it in a series correct?
    if i connect the ammeter in parallel what would happen?


    second if i were to connect a voltmeter i would connect it in parallel?
    if i connect the voltmeter in series what would happen?

    An ammeter is basically a short circuit, and a voltmeter is an open circuit. Can you answer the questions for us now?

    umm if you place voltmeter in series you would measure not voltage because, the voltage at two points are the same..

    im not sure about ammeter tho...

    Normally you place the voltmeter across whatever two points you want to measure the difference in voltage. You place an ammeter in series with a circuit branch to measure the flow of current through that branch.
