Problem 15MCQ
If ammeters and voltmeters are not to significantly alter the quantities they are measuring,
(a) the resistance of an ammeter and a voltmeter should be much higher than that of the circuit element being
measured.
(b) the resistance of an ammeter should be much lower, and the resistance of a voltmeter should be much
higher, than those of the circuit being measured.
(c) the resistance of an ammeter should be much higher, and the resistance of a voltmeter should be much
lower, than those of the circuit being measured.
(d) the resistance of an ammeter and a voltmeter should be much lower than that of the circuit being
measured.
(e) None of the above.
