What is current gain?
current gain
What is the symbol and unit of measurement of current intensity?
the symbol of current density is 'J'. & its unit is (Amp/m^2)
What is the current gain value of BC 148 transistor?
The hFe (current gain) on the BC148 ranges from a minimum value of 20 to 100, depending on collector current, with a maximum value of 300.
Why does a CE amplifier have a high gain?
GAIN is a function of load current but basically a small current in the base will make a big change of collector current therefore making a transistor a voltage amplifier as opposed to a current amplifier
What is the voltage gain of the 2n2222 amplifier?
A: The gain of a transistor is not linear and even that varies from component to component. The gain can vary greatly depending on the Ic current and the load. Manufactures only give out a typical gain for a particular current. As a rule the lower the Ic current the higher the gain. To really find out what a particular transistor characteristics are a tektronik curve tracer is used.
What is current gain?
current gain
How do you calculate the current gain of a transistor JFET?
FETs don't have current gain as no current flows through the gate. The gain of a FET is a voltage gain and is called mu.
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current. Voltage gain is the ratio of output voltage divided by input voltage. Nothing more complicated than that.
What is the symbol of electric current and on what basis it has been kept?
The symbol for electric current is I
What is the current symbol for the unit that measures current is?
A
Which configuration gives no current gain?
cc/ce/cb doesn't give the no current gain
What is the maxium current gain of common base amplifier?
If Beta is infinite, then the current gain will be unity.
What is the symbol for selenium atoms gain two electrons?
The symbol is Se(2-).
Why most often electric current is given the symbol 'I' capital 'i'?
I is the international (SI) symbol for electrical current.
A NPN transistor connected in common base mode has a current gain of 0.98 if it is now connected in common emitter mode what is the current gain?
The current gain in CE mode called as beta (ß) Tha current gain in CB mode called as alpha (A) ß= A/(1-A) =0.98/(1-0.98) =49 the current gain is 49 in CE mode
What is the base current when current gain is 150?
1
What unit is used to measure electric current and what is its symbol?
Amperes are the units; 'I' is the symbol chosen to represent amperage.
