What happens inside a voltmeter when you switch it from a lower to a higher voltage range?
When you switch a voltmeter from a lower to a higher voltage range, an additional resistor is added in series with the meter, increasing the voltage necessary to create the same voltage drop across or current flow through the actual meter movement.
Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.
Which type digital voltmeter is the of fatest all digital voltmeter?
You mean fastest? Digital voltmeter gives reading in seconds.
What is voltmeter?
A voltmeter is a measuring instrument that is used in the measurement of the electric potential in volts.
Why there is an extension range of voltmeter when a series resistance not equal to voltmeter is used?
why is extention
What quantity does the voltmeter measure when the switch is open?
Voltage
What would cause the sun roof of a 91 celica gt to not work?
Check for a bad fuse. If fuse is fine pop off the switch and check the switch with a voltmeter. Also check for voltage (12 Volt) to the switch with the voltmeter. If all is well to this point move to the roof motor and repeat tests.
Why would your AC not come on when you turn the knob?
You either have a bad switch or you need to check your fuse or relay for your a/c. To check your switch: you need a multimeter or voltmeter. You'll need to get to the back of your switch, keep it plugged in and find your power wire to the switch. Then put the positive end of the voltmeter in the back of the connector into the power(don't push to hard or you'll damage the connector). Then put the negative end of the voltmeter on a good ground on your frame or something that touches your frame. You should get a voltage reading of 12 volts. If there's no voltage than somethings wrong with the wiring up to your switch. If there is voltage, than you need a new switch.

Dim lights stay on?
If the dim lights are continuously staying on there may be an issue with the dimmer switch. The actual switch may be jammed in the on position. Check the switch with a voltmeter and see if there is continuous power coming from it.
Why are none of the headlights are working on lowbeam but when switched to highbeam all for of them come on for a 1988 brougham?
I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages. I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages.
Symbols of the electric circuit?
there is a symbol of bulb,galvanometer,voltmeter,ammeter,gong,paperclip,switch,wire,solenoid,bulb and armature
What do you mean by range of voltmeter?
It is the maximum voltage to which it has been calibrated, but this may be set out in separate ranges selected by a switch on the front panel.
Voltmeter in series?
No. Voltmeter in parallel. Ammeter in series.
A DC voltmeter has a resistance of 20000 ohms per volt What is the resistance of the meter if the range selection switch is set on the 250 volt range?
5 megohms
What is a dc voltmeter?
It is a voltmeter which can only measure direct current.
