How much power does bulb A dissipate when the switch is open?
Problem 23.60
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 0.3Ω resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed. Assume E=2.0 V.

Resistors connected in series generally always
select all that apply
1
dissipate more power than when hooked up in parallel
2
offer the biggest effective resistance compared to any other way
of connecting them
3
dissipate the same amount of power each
4
have the same voltage across them
5
have the same current through them

When switch S in the figure is open, the voltmeter V of
the battery reads 3.08 V. When the switch is closed, the
voltmeter reading drops to 2.98 V, and the ammeter A reads1.64 A. Assume that the two meters are
ideal, so they don't affect the circuit.a) Find the emf.b) Find the internal resistance of the batteryc) Find the circuit resistance R.

When a firm wants to expand, how does it decide on how much of
each of its inputs to increase? Does it make sense to only increase
one of its inputs? What happens when the price of an input rises or
falls? Does the firm stop using that input or adjust how much of it
is used?
