Yes. By convention, the horizontal line is deflected upward for positive voltages and down for negative.
With no input, adjust the line to co-incide with a central line on the graticule.
A varying voltage that remains positive will be deflected above the line. A voltage that transits from positive to negative will draw above and below the line.
What else can I help you with?
Compare an anode and a cathode?
The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.
How you can prove the Peak voltage?
Use an oscilloscope. That shows the voltage waveform and you can read the peak value.
How do electrons flow in an electric circuit in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
2 12 volt batteries to 24 volt?
To get 24V from 2 12 V battery's Yo hook up the positive pole + of one of the battery's to the negative pole - of the other one. you will be left with a positive pole on each battery wit no connection on them The voltage between them is 24. If you want the battery to have the same voltage but have more amperage you connect positive to positive and negative to negative.
Why do telecommunication systems use negative voltage?
negative polarity is achieved by grounding the positive terminal of power supply system and the battery bank. This is done to prevent electolysis depositions.
How rays can be produce by cathode ray oscilloscope?
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
What does the term oscilloscope mean?
The meaning of the word oscilloscope is a device used for viewing oscillations, electrical current or voltage or, with a display on the screen of a cathode-ray tube.
What will you do to measure voltage which is greater than voltage limit of the cathode ray oscilloscope?
change your resistance, its a little button, or if you are using an older oscilloscope, its a knob that will lower the sensitivity of the display. if it is something way higher than the oscilloscope can measure, you may have to run a resistor or transformer in the line.

What are the meanings of positive and negative reduction potentials?
the meanings of positive and negative voltage
Does battery voltage combine when you use more than one?
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
How can you maesure using oscilloscopes?
To measure using an oscilloscope, connect the oscilloscope probe to the signal source. Adjust the time and voltage scales on the oscilloscope to properly display the waveform. Use the cursors and measurements feature on the oscilloscope to measure parameters like frequency, amplitude, rise time, and pulse width.
What is the vertical axis on an oscilloscope measure?
The vertical axis on an oscilloscope measures voltage. It represents the amplitude of the electrical signal being analyzed, with the height of the waveform indicating the voltage level at any given point in time. The vertical scale can be adjusted to display different voltage ranges for better visualization of the signal.
How the unstable waves stables in oscilloscope?
Unstable waves can be stabilized on an oscilloscope by adjusting the trigger level and trigger slope settings. By setting the trigger level to a specific voltage and selecting the appropriate trigger slope (rising or falling edge), the oscilloscope will only display the waveform when it meets these trigger conditions, helping to stabilize the display of the waveform.
What will happen when the terminal of the volmeter are inversed and used to read the voltage of the DC supply?
Depends on the voltmeter. Some meters will display a positive voltage no matter how the leads are attached to the source. Others may indicate a negative voltage if leads are reversed.Another AnswerAn analogue voltmeter will always read downscale (i.e. 'backwards') if connected the wrong way around.Digital voltmeters generally indicate the correct voltage, but display a negative sign to indicate that the polarity is the wrong way around.Don't forget, when we say 'negative voltage', we are referring to its direction. Voltage, which is simply another word for 'potential difference', and it cannot be positive or negative in the sense of 'charge'.
Why negative supply is more prefer then positive supply?
A: actually it is the other way around usually negative voltage is a biasing scheme. Most design are begun with a positive voltage in mind. Not that a negative voltage will not work it is just people think positive
What is a positive DC voltage?
A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.
