Initially bulbs A and B in (Figure 1) are glowing.
What happens to bulb B if the switch is closed? Does it get
brighter, stay the same, get dimmer, or go out?
When switch S in the figure is open, the voltmeter V of the battery reads 3.06 V. When the switch is closed, the voltmeter reading drops to 2.96 V, and the ammeter A reads 1.6 A. Find the internal resistance of the battery. Assume that the two meters are ideal, so they don't affect the circuit.

In the circuit shown in the figure, bulbs A and B are
glowing.Then the switch is closed. What happens to each bulb? Does
itget brighter, stay the same, get dimmer, or go out?
Explain.
When switch S in the figure is open, the voltmeter V of
the battery reads 3.09 V . When the switch is closed, the voltmeter reading drops
to 2.96 V , and the ammeter A reads 1.66 A . Assume that the two
meters are ideal, so they do not affect the circuit. (Figure 1) -
From that we find that emf E = 3.09 V.Find the internal resistance r of the battery.
When switch S in the figure (Figure 1)is open, the voltmeter V
of the battery reads 3.13 V . When the switch is closed, the
voltmeter reading drops to 2.99 V , and the ammeter A reads 1.70 A
. Assume that the two meters are ideal, so they don't affect the
circuit.1) Find the emf.2) Find the internal resistance of the battery.3) Find the circuit resistance R.
By what percent does the
current through A change when the switch is closed?
I just need Part C. I can't figure it out.
Problem 28.54 For an ideal battery (r 02), closing the switch in (Figure 1) does not affect the brightness of bulb A. In practice, bulb A dims just a little when the switch closes. To see why, assume that the 1.50 V battery has an internal resistance 0.80 2 and that the resistance of a glowing...
