Line Splitters - line splitter

but you want to measure current the most accurate way to do that is with a digital multimeter a digital multimeter contains a precision resistor and the current actually flows across that resistor and displays the value the problem with digital multimeters is you actually have to break the circuit and insert the meter in series to get that current measurement that's fine when you're working on electron small electronics or bread boarding and developing things it's not practical if you're trying to measure current on something like a light bulb and a cord or an appliance or an Accord in your house I've got a couple light bulb switched on I'm drawing 2.4 amps here and I actually had to cut the wire in order to put this meter in series to measure that current so that's where something like a clamp meter comes in a clamp meter lets you actually clamp around the wire and measure current that
