A cell of emf 3.4V and internal resistance `3Omega` is connected to an ammeter having resistance `2Omega`. and to an external resistance of `100Omega`. When a voltmeter is connected across the `100Omega` resistance the ammeter reading is 0.04A. Find the voltage read by the voltmeter and its resistance. Had the voltmeter been an ideal one what would have been its reading ?
