What can resistance do?
U didn't clearify resistance in what aspect. If u mean electrical resistance,Resistance is phenomenum which describes the limitation of the flow of electric current in an electrical circuit. According to Ohms law (V=IR),the value of resistance is directly proportional to the value of voltage and inversely proportional to the value of current.That is,as the value of resustance increased,voltage also increases;also if the valur of resistance increases,the current reduces(as in I=V/R)
What is the difference between voltage gain obtained with bypass capacitor and without the bypass capacitor?
A: A TRANSISTOR gain is determined by current flow on the collector by adding a resistor to the emitter this current flow is reduced by adding or bypassing this resistor with a capacitor the net effect is that this emitter resistor will be reduced in value as frequency increases therefore change gain as a function of frequency input
How does one use the Perl chomp function?
The Perl Chomp function is a programming function that remove the "newline" character at the end of the string. One can use the Perl Chomp function to remove any character that has the same value as the current one.
If the resistance increases what will happen to voltage and current?
If you have a simple circuit. For eg: One voltage source and one resistor, then the voltage of the circuit will always remain the same, the current however will decrease following Ohms' Law V=I*R. If we have a current source instead of a voltage source, we are forcing the current to be a certain value so if we increase the resistor value the current will remain the same but the voltage will increase.
What is a resistor in electricity?
Resistor is an eletrical and electronical part whose function is to decrease the value of the voltage in a circuit, consequently reducing the value of the current, which is measured in Amperes.
A function that decreases proportionally to it's current value. The smaller the function gets the faster it decreases.?
The logarithmic function is one such.
What is a positive gradient in math?
A positive gradient is a characteristic of a function whose value increases as the value of the argument increases. So, if y is a function, f(x), of x, then an increase in the value of x is accompanied by an increase in the value of y.
Can the work function depend upon the wavelength of light?
Yes, definitely . For the given metal of particular work function, decrease in wavelength of the incident beam increases the maximum value of kinetic energy with which the photoelectrons are emitted, but the photoelectric current remains the same, stoppage voltage increases.
What does exponential growth refer to in Mathematics?
Exponential growth in mathematics refers to how the growth rate of a value is proportional to the current value. Therefore, as the current value increases, the growth rate increases by a larger amount each time.
Is the vi characterreistics curve of a pn diode is linear or exponential?
A diode has a fixed voltage drop (c), and if the voltage is less than that, no (or very little) current flows. Once the voltage increases above the voltage drop, the current increases exponentially as the voltage increases. A function that models this is: I = exp(b*(V-c)) where V is the voltage, I is the current, c is the voltage drop and b is a parameter that determines how fast the current increases; the value of b varies from one diode to another
What happens to the value of y as x increases in the function y equals 2x-5?
7
Why doesn't the value of the fraction change when you simplify it?
Because it is proportionally the same value.
The value of the determines whether the graph of an exponential function increases or decreases from left to right?
base
What is a positive or negative relationship on a graph?
If a function Y is dependent on X. if X increases in value then Y also increases then we call this a positive relationship. If X increases in value then Y decreases or vice versa then we call this a negative relationship.
If the value of resistance increased then?
If the resistance is increased the current, which is inversely proportional, decreases and, the voltage drop increases.
What is ment by early effect in transistor?
For a fixed value of Vbe,as Vce increases the reverse bias on the collector base junction increases,hence the width of the depletion layer increases.therefore base width decreases,so collector current increases. To minimise this effect base must be heavily doped than collector CONSEQUENCES: ->due to early effect collector current increases with increasing Vce,for a fixed value of Vbe. ->the base current do not change significantly Early effect=collector current * correction factor
What is an exponetial function?
Any function that can be written in the form AeBx. Instead of e, any other base greater than one can be used (since that can be converted into the form indicated above). Note that B can be positive (the function value increases), or negative (the function value decreases).
