Consider the circuit shown. (Intro 1 figure) All wires are considered ideal; that is, they have zero resistance. We will assume for now that all other elements of the circuit are ideal, too: The value of resistance is a constant, the internal resistances of the battery and the ammeter are zero, and the internal resistance of the voltmeter is infinitely large. 
Intro 1. 
Part A What is the reading V of the voltmeter? 
Express your answer in terms of the EMF .
Part B The voltmeter, as can be seen in the figure, is connected to points 1 and 3. What are the respective voltage differences between points 1 and 2 and between points 2 and 3? 

Part C What is the reading I of the ammeter? Express your answer in terms Emf E  and R. Now assume that the battery has a nonzero internal resistance r (but the voltmeter and the ammeter remain ideal). (Intro 2 figure)
Part D What is the reading of the ammeter now? r Express your answer in terms of E, and R.
Part E What is the reading of the voltmeter now? E, r Express your answer in terms of, and R

To understand how to compute power dissipation in a resistive circuit. (Figure 1)The circuit in the diagram consists of a battery with EMF, a resistor with resistance R, an ammeter, and a voltmeter. The voltmeter and the ammeter (labeled V and A) can be considered ideal; that is, their resistances are infinity and zero, respectively. The current in the resistor is I, and the voltage across it is V The internal resistance of the battery rint is not zero. figure

In the figure below, a voltmeter of resistance RV=300, and an ammeter of resistance RA =3.00 Ω are being used to measure a resistance R in a circuit, that also contains a resistance R0 = 100 Ω and an ideal battery of emf -18.0 v. Resistance R is given by R v, where v s the voltmeter reading and The current in resistance R However, the ammeter reading is not I, but rather, which is, plus the current through the voltmeter. Thus, the ratio of the two-meter readings is not R, but only an apparent resistance R' = Vr If R 75.0 Ω: (a) What is the ammeter reading? (b) What is the voltmeter reading? 

The circuit in the diagram consists of a battery with EMF , a resistor with resistance R and an ammeter and voltmeter. The voltmeter and ammeter can be considered as ideal that is their resistances are infinity and zero respectively. The current in the resistor is I and the voltage is V. The internal resistance of battery is not zero.
