Multimeters!!

Recently, we've been dealing a lot with these things called multimeters in physics class.

Well, what is a multimeter, you ask?
A multimeter is an instrument designed to measure electric current, voltage, and resistance.

We have been using multimeters in class to understand currents, voltages, and resistances in schematic circuits drawn on the board with a D battery as the voltage source. We learned that when you use a multimeter, you must measure "voltage across, current through". When measuring voltage, you measure from one side of the resistor (lightbulb, wire, etc.) to the other. When measuring current, you must break the circuit and connect the probes between to measure the flow.

What can you use a multimeter for other than for physics experiments and diffusing bombs?
You can use a multimeter for all sorts of things. Within a circuit in your house, you can use the multimeter to check where the break or shortage. You can save money by getting straight to the problem instead of hiring someone else to do it or throwing the device away! For example, if you have a device that is using an ac/dc converter that stops working, how can you tell if it is the converter or the device? Instead of just buying a new device or converter, you can use a multimeter to understand the root of the problem!
You can also use a multimeter to test if your batteries still have voltage in it. Multimeters are useful for testing ac/dc converters, fuses, lightbulbs, wall switches, wall outlets, and most electronic devices in your household!
