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.
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.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
What will happen to the resistance and the brightness if you add a light bulb to the circuit?
If a rheostat is connected in parallel with a light bulb, the setting of the rheostat should have no effect on the performance of the light bulb, as long as the power supply is able to maintain its output voltage and deliver the current demanded by their parallel combination.
Four 9-volt batteries are connected in parallel how much voltage is active across the circuit?
Four 9v batteries connected in a parallel will still emit 9 volts because you are not increasing the voltage, you are increasing the life. To increase the voltage of four 9v batteries, you must connect them in a series; that series will emit 9v X 4(batteries), which equals 36 volts.
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.
Three cells have voltage of 15V 18V and 20 V What is the total voltage of the cells when they are connected in parallel?
Sources with different voltages should never be connected in parallel, you would have a difference of potential. Any time you have a difference of potential connected together you will have sparks, which could cause the batteries to explode.

Why is the current source connected in series only?
Current sources should not be connected in series. It's okay to connect them in parallel.
When 2 alternators are connected in parallel what is the resultant terminal voltage of the two alternators?
Since the alternators are in parallel, the resultant voltage should be the same as either alternator - exactly as it would be if two batteries are connected in parallel. Voltage remains the same but current capacity is doubled. I would recommend connecting the alternators through a network that will balance the load between them.
How do you connect 2 6 volt batteries in parallel to make 12 volts?
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.
How voltmeter works?
It is connected in parallel and measures potential difference.
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?
Why should ammeter still be connected in a series despite the fact that the bulbs are already connected in parallel?
Because the ammeter connected in parallel will act as a short circuit.
Should a Voltmeter always be connected in a series with a component?
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
