The capacitor is there to block any dc voltage that might be applied to the input terminal, which could cause damage or upset the biassing if it was allowed through to the base.
What else can I help you with?
Can you use semiconductor as a capacitor?
Transistor either increases or decreases current.. Capacitor stores energy
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
Is a transistor a small electronic switch?
A transistor is used to switch electronic signals.
Why capacitor is used before UM66 in circuit for melody generator?
We used capacitor in UM66 because capacitors are used to store the energy, and hence when we press the switch it will charged the capacitor and energy stored in it, and after releasing the switch it releases the energy. So, we can use the capacitor to store the energy.
Why you use capacitor before connecting transtitor?
Before connecting to the transistor we use a capacitor becausefor the transistor to amplify we should first apply DC biasing so that we can set an operating point to itso once the transistor is biased DC currents flow in the whole circuitryAll the AC signal source are shorts to the DC currents so we employ capacitor for two reasons1.As capacitor blocks DC and allows AC it is connected for not moving the DC operating point of the transistor and making it fixed since if any small DC part arises in the signal it leads to the change of operating point and our amplification procees gets affected2.To block the already present DC currents in the circuitry for not getting away and making it fixed
Can you use semiconductor as a capacitor?

What is the difference between capacitor and transistor?
transistor either increase or decrease current bt capacitor stores the energy
How do you set up an RC circuit that will keep a 12V lamp on for 4 seconds after depressing the switch?
Use a transistor to drive a small relay. When the switch is pressed it should turn on the transistor and at the same time charge a small capacitor. Discharge the capacitor over 4 second time period with a resistor. You will have to experiment with resistors to find one that gives an acceptable discharge rate. Note, if the 12V lamp is running DC you can drive it directly with the transistor and forget about the relay.
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
Resistor and capacitor built circuit for alarm switch?
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
DC blocking in a transistor is achieved by?
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
Is a transistor a small electronic switch?
A transistor is used to switch electronic signals.
What is use of bipolar junction transistor?
amplifier, switch, oscillator, etc.
What does a time activated switch use?
A time activated switch could use pneumatics or an resistor capacitor circuit.
Function of resistor capacitor and transistor on integrated circuit?
resistor
