What else can I help you with?
When measuring the potential difference across a componet you need?
A voltmeter connected in parallel.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
A switch is connected in a series with a 75-W bulb to a source of 120V. what is the potential difference across the switch when it is closed?
If the switch, light bulb, and source are all connected in series and the switch is ideal (has no resistance), then the switch acts as a short. There is no potential difference across the short.
What is a difference between neutral earthing and body earthing?
here is no major difference between earthing and Grounding, both means "Connecting an electrical circuit or device to the Earth". This serves various purposes like to drain away unwanted currents, to provide a reference voltage for circuits needing one, to lead lightning away from delicate equipment. Even though there is a micro difference between grounding & earthing.Earthing and Grounding both is refer to zero potential but the system connected to zero potential is differ than Equipment connected to zero potential .If a neutral point of a generator or transformer is connected to zero potential then it is known as grounding. At the same time if the body of the transformer or generator is connected to zero potential then it is known as earthing.
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
How is a voltmeter connected in the circuit to measure the potential difference between two points?
The voltmeter is connected in parallel between the two points whose potential difference is required.
When measuring the potential difference across a componet you need?
A voltmeter connected in parallel.
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.
What happens when two or more capacitors are connected in parallel across a potential difference?
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
What happens when two or more capacitors are connected in series across a potential difference?
When two or more capacitors are connected in series across a potential difference, the total capacitance decreases and the total voltage across the capacitors is divided among them based on their individual capacitances.
How is a voltmeter connected in a circuit to measure electrical potential difference?
A voltmeter is connected in parallel to the component or circuit being measured to measure the electrical potential difference, also known as voltage. This allows the voltmeter to read the voltage across the component or circuit accurately.
A switch is connected in a series with a 75-W bulb to a source of 120V. what is the potential difference across the switch when it is closed?
If the switch, light bulb, and source are all connected in series and the switch is ideal (has no resistance), then the switch acts as a short. There is no potential difference across the short.
What is the difference between capactive voltage transformer and potential transformer?
A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
What does mean by ferroresonance?
Ferroresonance is a phenomenon that can occur in electrical systems when there is a combination of non-linear characteristics from inductive elements and capacitive elements, resulting in high voltages and potential damage to equipment. It can occur in power systems during switching operations or when equipment is disconnected or connected abruptly. Mitigation measures include the use of resistors, damping circuits, and proper system design.

How voltmeter works?
It is connected in parallel and measures potential difference.
