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 will normally have the larger resistance a voltmeter or an ammeter?
A voltmeter has the large resistance.The voltage across any component can be measured if & only if the terminals of that component will be open and this will we can acheiv if we connect the high resistance voltmeter across the open terminals of that component to measure the voltage.
When you measure voltage with a voltmeter you must break open the circuit and connect the meters test leads in series with the other circuit components?
Sounds more like you're trying to measure resistance...
What happens if the switch is open?
If the switch is open, current does not flow.
A bulb is connected to a battery having a potential difference of 6 V A voltmeter is connected across the bulb What is the reading on the voltmeter when the bulb burns out?
Assuming you're referring to a simple incandescent bulb . . .When the bulb burns out, the filament is open, and it is electrically no longer there.The voltmeter is then across the battery, which is open circuited, i.e. without a load.The meter measures the open-circuit voltage of the battery, nominally 6 V.
What quantity does the voltmeter measure when the switch is open?
Voltage

How do you measure with Multimeter a motor or integrated circuit IC for failure?
The voltmeter function if the circuit is energized or the ohmeter function if looking for short or open circuits

Why must voltmeter be connected in parallel with the circuit component?
Because, by definition, a voltage is the difference in potential between two different points. So the voltmeter must be connected across those points in order to measure that voltage -i.e. in parallel with the points.B
How would I fix stuck brake lights on 1999 Nissan Pathfinder?
1: check the switch that the brake pedal opens and closes when you (respectively) release and apply the brake. using a voltmeter, verify that no voltage passes when the switch is open (brakes unapplied) - if there is continuity when there should not be, then the switch is the problem. you will have to be more specific beyond "stuck" if this does not help you.

The source voltage.
