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.

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...

When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance
When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...

A battery provides a voltage of 8.00 V and has unknown internal resistance Rint. When the battery is connected across a resistor of resistance R1= 7.00 Ω , the current in the circuit is I1 = 1.00 A. If the external resistance is then changed to R2 = 5.00 Ω , what is the value of the current I2 in the circuit?
