<h2>Summary</h2>
<ul>
<li>Voltmeters measure voltage, and ammeters measure current.</li>
<li>A voltmeter is placed in parallel with the voltage source to receive full voltage and must have a large resistance to limit its effect on the circuit.</li>
<li>An ammeter is placed in series to get the full current flowing through a branch and must have a small resistance to limit its effect on the circuit.</li>
<li>Both can be based on the combination of a resistor and a galvanometer, a device that gives an analog reading of current.</li>
<li>Standard voltmeters and ammeters alter the circuit being measured and are thus limited in accuracy.</li>
</ul>
