20.1 Current

Note that the direction of current flow in Figure 20.3 is from positive to negative. The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move.

Measuring Internal Resistance of Batteries

In reality, several factors can limit a battery''s ability to act as an ideal voltage source. Battery size, chemical properties, age, and temperature all affect the amount of current a battery is able to source. As a result, we can create a better model of a battery with an ideal voltage source and a resistor in series.

how to measure the internal resistance of a voltmeter?

Using Ohm''s Law, calculate the following... Voltage measured by the meter, divided by the Current measured by the Amp-meter = Impedance. Example I measured 13.8 volts, and with another meter in series with the voltmeter, I measured the current through the voltmeter at 1.2 micro-amps. 13.8 V / 0.0000012 A = 11,500,000 …

Why does measuring the voltage drop across a thing not simply measure ...

Now as others have pointed out, in real life a battery is not an ideal voltage source. The voltage of a real battery changes depending on how much current is being drawn and how much charge is left. So in real life, adding a resistor can change the battery voltage. But the battery voltage and the resistor voltage will still be (almost) equal.
