What should the current be through a bleeder resister in a voltage divider circuit?

The current should be high enough to maintain the voltage at each division. Generally, the current should be ten times the load current or the voltage will be across the voltage divider.
If possible use regulators or zeners or regular diodes. I'm not saying dividers are bad but there are less current sensitive solutions.

What is a parallel curcuit?
A parallel circuit is a circuit where there is more than one path of which the flow of current can travel. It is also called a current divider as it divides the current since it splits the path.
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.
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
Why voltage divider biasing circuit is the widely used biasing?
In a voltage -divider circuit method for biasing a transistor , we have two resistors R1 and R2 a DC supply voltage VCC and other components like collector resistor , emitter resistor are also present.here biasing is done by the help of voltage drop across the resistorsto understand the reason behind the extensive usage of voltage - divider method we need to know about the term stability.Stability factor of a transistor is defined as the ratio of amount of change in collector current to the amount of change in the same collector current with the base open(leakage current due to minority charge carriers)lesser the stability factor ------ that type of biasing is more desiredthe stability factor for voltage divider method is nearly equal to one.
What is the advantages of variable resistor?
When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider. Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.
What is the current that flows through an unloaded voltage divider?
The Bleeder current.
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.
What is example of dependent source and independent source of voltage and current?
Boss its a circuit not a device, you can also create one of yours..... just use simple logic of voltage divider and current divider rules...-satendra.svnit@gmail.com
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
What is the operation of potential divider bias?
Thevenization of the divider circuit will help you see how it operates.
What happens to voltage in a parallel circuit?
Voltage can be divided by a voltage divider, also known as a potential divider. Scroll down to related links and look at "Calculations:voltage divider (potentiometer) - damping pad - loaded and open circuit (unloaded) - voltage drop at the voltage divider"
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 a parallel curcuit?
A parallel circuit is a circuit where there is more than one path of which the flow of current can travel. It is also called a current divider as it divides the current since it splits the path.
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.
If all the resistors in a voltage divider circuit are doubled the output voltage will be half?
No, the output will remain constant. If you double all the values, the divider ratio will not change, and it is the ratio that determines the output voltage. The current flow through the divider itself will change, it will be half the original value. This could affect the accuracy of the divider. For the same accuracy, the minimum load resistance would be double the original value.
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.
What is the purpose of a resistor?
A variable resistor is used in cicuits to vary the current passing through the resistor. It is commonly used to change the value of current across a circuit, or to act as a voltage divider. They are commonly equiped with a knob outside of a cabinet, to enable the user to adjust the operation of a circuit, like a volume control on a radio or amplifier.
