What is the purpose of the voltage divider control in oscilloscope?
Wiki User

This control reduces the amplitude of the applied signal to a point where the whole signal can be displayed on the oscilloscope screen. The amount of voltage reduction is marked on this control switch so that it can be used as a voltmeter.

What is the voltage divider theorem?
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
Why current cannot be measured directly using an oscilloscope?
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
What are advantages of voltage divider bias over the other types of biasing ci?
You can use more than one type of voltage divider in it. It can sometimes get mixed signals with all the things going on.
What you will 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 application of voltage divider biasing?
To get reasonable gain without losing stability of circuit. ANSWER: Is to reduce the input to a lesser value or to match signals impedance
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
What is the voltage d?
voltage divider
What is the difference between voltage divider and potential divider?
its the same
What is a voltage divider circuit?
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
What is the definition of stiff voltage divider?
A voltage divider in which the base current is small compared to the current in R2 (resistor in other path to ground) is said to be a stiff voltage divider because the voltage is relatively independent of different transistors and temperature effects.
How do design a high voltage voltmeter?
Use a voltage divider and an standard high input impedance voltmeter connected to the low voltage output tap of the divider. Just check that: a) the voltage divider has enough resistance to minimize loading of the voltage source (The voltage divider resistance should be as high as possible). b) the voltmeter's input impedance is at least 10-20 times larger than the output resistance (impedance) of the divider. If necessary add a high-input impedance amplifier or a transducer between the divider output and the voltmeter. What is high voltage for you?

What is the difference between a voltage divider circuit and voltage regulator I was told if the circuit consumes low current then the voltage divider can be used what does that mean?
A: that is true for less current a divider is OK it has to do with the series resistance and loading if the loading is forever fixed and the source is also fixed at a value then a divider can be used no matter what the current is.
How can I drop voltage from 19.5 volts to 18.5 volts?
You might consider a resistive voltage-divider, using two resistors (tap output from between them), or using a voltage regulator circuit that you can adjust with precision for your purpose (e.g., LM340), depending upon whether you mean DC or AC voltage and what size load you might be servicing. For a voltage divider, check the wikipedia page for how to calculate the ratio of resistors.
What is voltage divider circuit?
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
Why current cannot be measured directly using an oscilloscope?
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
