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. Assume E = 1.7 V. Figure 1 of 1 0.3.2 A 6.0 22 16.02 E Part A How much power does bulb...

Batteries are not perfect. They can't deliver infinite current. As the current load on a battery gets larger, the voltage output gets smaller. We can represent this by treating batteries as if they have some small internal resistance. The circuit below shows a battery hooked up to a resistor, a voltmeter (for measuring voltages), and an ammeter (for measuring currents). When you put a measuring device on something, like a circuit, you don't want to change the circuit. So this...
