Because if you connect an ammeter in parallel with a component, you are actually creating another branch, thereby reducing the actual current through the component.

If you connect an ammeter in parallel you are creating a low resistance current path around the component your trying to test. Your tester has a low resistance so you dont effect the current flowing through the component your trying to test. When a current tester is in parallel, it is a dead short, and you will probably burn out your tester.

A voltage tester is connectect in series so you can test the voltage dropped across the component in question.Voltage in volts equals the current through the component in amps times the resistance of the component in amps.If you know the resistance of the component, and the voltage across it you dont need to use a ammeter to find the current.Just devide the voltage by the resistance.

Think of electricity as water and an ammeter as measuring the volume of water and a voltermeter as measuring the pressure

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

### How do I connect a 5 wire digital Volt/Ampmeter from my solar panel to my battery.

If you can identify which is the voltmeter and which is the ammeter, it should be simple. Say the solar panel has output wires of Red (positive output) and black (negative output). The ammeter goes in series with the load (cut the red wire and insert there). Voltmeter goes between Red (solar panel side usually) and Black. That accounts for four wires. The fifth wire may be an earth ground but I'd be guessing. If you can post a link from the manufacturer, I will comment further.

### How do you hook up amp meter for battery charger

DO NOT CONNECT IT to both poles + - !!! the amp meter have very small internal Ressistance, it blows of :) Connect it like in the picture

### Battery light on and off

The battery light means the alternator is not charging the battery. The charging system would need to be checked out when the light is on.

### A voltmeter should be connected in a series with a component?

A Voltmeter is connected in parallel with a component because in voltage mode it has a high impedance and measures the voltage drop across the component being tested and does not affect any parts of the circuit.
An Ammeter on the other hand is connected in series with a component because in current mode it has a low impedance and measures the actual current through the component being tested

### Need apair passive crossover for pair of maxp64 600 watts

You can easily make one yourself. All you need are two non-polar capacitors of about 1 Farad each. Radio Shack and any respectable electronic component store have them. For a high pass filter (AKA crossover) connect in series with the speaker wires. For low pass operation like a sub-woofer, use it in parallel with the speaker.

### Readings of Ammeter and Voltmeter.

The voltmeter will display 3V and the ammeter will show a small amount of current this is the current being used to swing the needle or in a digital meter the current used to get a sample.

### Why must voltmeter be connected in parallel w/ circuit component

When connected in parallel it reads the voltage drop across said component.
When connected in series the current flows thru the meter allowing the measurement of the current flowing thru circuit.
Hope that helps.

### Why must be a voltmeter be connected in parallel with the circuit component?

to check voltage or Resistance that's the way it has to ne.
it is only used in series when checking amperage.
usually not over any circuit over 10 amps; depending on the

### Weak reception, broken surface mount component

You can not find any schematics for the Magellans.  The schematics are classified.  Even when repairing GPS's for Magellan we didn't receive full schematics.  If your talking about the RF cable connector on the I/O Board (the board attached to the rear housing), then it's an easy solder fix.  For the capacitor/resistor:  I'm not sure where you found the capacitor origin, but if it's black with four legs coming off and parallel with the IC then tell me and I'll msg you back the rest.
