For an ideal battery (r = 0 Ω), 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
r = 0.90 Ω and that the resistance of a glowing bulb is
R = 8.00 Ω.

please help with A and B
If the battery in (Figure 1) were ideal, lightbulb A would not dim when the switch is closed. However, real batteries have a small internal resistance, which we can model as the 0.31 resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed.

In the circuit shown in (Figure 1) switch Si has been closed a long time while switch S2 has been left open. Then S2 is closed at the same instant when S1 is opened.
In the circuit shown in (Figure 1) switch Si has been closed a long time while switch S2 has been left open. Then S2 is closed at the same instant when S1 is opened.Part A Just after S2 is closed, the current through the resistor is 12.0 A and its rate of decrease is di/dt = 36.0 A/s. How long does it take the current to decrease to Figure 1 of 1 6.00 A, one-half its initial value?
