How to Use a Multimeter, Part 4: Measuring Current (amperage)
First, we discussed how to use a multimeter for measuring voltage, or simply verifying that voltage is present. Last week, we addressed measuring resistance—verifying that a wire is continuous and not broken somewhere. Today we''re discussing how to use a meter to measure current, also referred to as amperage. Let me …
Testing Batteries With a Multimeter
This way current will flow through the resistor and we can take a voltage reading as this occurs. If the battery is still good, then the voltage level will only drop slightly. For example, this battery has a rated voltage of 1.5 volts.

You can''t measure it by sticking an ohm-meter on a battery, but you can infer it by measuring the battery voltage while it''s under a load. You need a load appropriate for the battery voltage and current capability, so you might use an automotive incandescent bulb for a small 12V lead-acid battery, or an LED for a coin cell.

19.2: Electric Current
Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
3 Ways to Measure Voltage
Voltage is a measurement of potential electric energy between two points. You can measure the voltage of household circuitry or batteries using a digital multimeter, an analog multimeter, or a voltmeter. …
6.5: Electrical Measuring Instruments
Analog and Digital Meters You may encounter two types of meters in the physics lab: analog and digital. The term ''analog'' refers to signals or information represented by a continuously variable physical quantity, such as voltage or current. An analog meter uses a galvanometer, which is essentially a coil of wire with a small resistance, in a magnetic …
Intro Lab
Project Overview In this project, you will learn how to use a voltmeter to measure voltage. Typically, the voltmeter is one of the functions of a multimeter, which is an electrical instrument capable of measuring …
