Question
Transcribed Image Text:25.54. In the circuit shown in
Fig. P25.54, R is a variable resistor whose
value ranges from 0 to co, and a and b are
the terminals of a battery that has an emf
E = 15.0V and an internal resistance of
4.00 2. The ammeter and voltmeter are
idealized meters. As R varies over its full
range of values, what will be the largest
and smallest readings of (a) the voltmeter
and (b) the ammeter? (c) Sketch qualita-
tive graphs of the readings of both meters
as functions of R.
