Why should you leave the thermometer in the liquid while you are measuring its temperature?
The reading is not accurate if it is not in the liquid that you are measuring. Once you take it out, the temperature will be measuring the air.
How a meter would be connected in a circuit to measure the voltage at a light bulb?
"Voltage" is the difference in electrical potential between two points in a circuit.If the voltage across the light bulb is what you want, then first make sure thatthe meter in your hand is a voltmeter, and then touch each probe of the voltmeterto one of the connections on each side of the light bulb.If you want to determine whether power is getting to the light bulb, you stillhave to do it by measuring the difference in voltage between two points. Youcould use your voltmeter to measure the voltage between one connection atthe bulb and one connection at the switch. If the power is getting from theswitch to the bulb, then the voltage between the switch and the bulb shouldbe zero (or very small).The voltage between the two connections to the switch should be zero whenthe switch is ON, and mains voltage (115 or 220) when the switch is OFF, etc.I have worked alongside individuals in the past who claimed that they coulddiscern the presence of voltage, and even measure it, by licking their fingerand touching it firmly to the circuit point in question. I don't know how manyof them are still alive, and I strongly recommend AGAINST that technique.
What happens to the voltage as more bulbs are added in series?
The total voltage should not change in this case.
Why is voltage considered to be a forcelike quantity how is it produced?
Voltage is the "force" that pushes the electrons or other charge carriers, producing a current. It should be noted that voltage does not have the units of force; thus, the traditional name "emf" (electromotive force) is misleading.
Describe the proper placement of a voltmeter in a circuit?
A voltmeter should be connected in a parallel connection
When measuring voltage the probes should be connected in?
can some one please tell me when measuring voltage the probes should be connected to sequence or series?
How should a ammeter and voltmeter be connected in series?
no. you want to measure across the desired circuit segment. whether you are measuring voltage drop or current.
When measuring resistance what should done to the supply voltage?
supply should be off
How do you check dc voltage... series or parallel?
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.
Should Power sources connected in parallel have the same voltage rating?
yes
In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
How voltmeter works?
It is connected in parallel and measures potential difference.
Two voltage sources can be connected in parallel when they are equal in?
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
When measuring an unknown voltage with a multitester or analog VOM you should first?
Go to highest scale on AC range
What voltage is provided by two 1.5 v cells connected in series. There are two answers to this question?
3.0 v ... there should be only one answer to this question.==========================Answer #2:If they're accidentally connected nose-to-nose or tail-to-tail,then their combined series voltage is zero.
How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
