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.
What causes the ripple voltage on the output of a capacitor-input filter?
Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.
Why capacitor in transistor amplifier circuit at input?
Because capacitor not allow to pass dc voltage,but capacitor allow ac voltage and signal.Purpose is to block dc voltage.That is coupling condenser.
Why capacitor reduce gain of ce amplifier?
Where is this capacitor in the circuit?A capacitor across the emitter bias resistor actually increases the AC gain because it bypasses that resistor, by increasing the ratio of collector impedance to emitter impedance which determines the amplifier voltage gain.A capacitor across the base input resistor actually increases the AC gain because it bypasses that resistor, by decreasing the attenuation of the input signal by the input circuit network.
Will voltage drop across a capacitor?
basically a capacitor will charge to the input DC level however it will mathematically never happen since capacitors charge at a certain rate the voltage drop across a capacitor will follow the R C time constant or 63% of the applied voltage for a unit time.AnswerIn the case of an a.c. supply, yes, there will be a voltage drop across a capacitor. In the case of an 'ideal' capacitor, this will be the product of the load current and the capacitive reactance of the capacitor.
What is the value of capacitor voltage and current after 5 time constant?
After 5 time constants, capacitor voltage/current will be about 99.3% of the input step change.
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.
What are the steps behind installing a car audio capacitor?
First, the capacitor must be charged. Use a voltmeter, and when it reaches 12 volts, the capacitor is charged. The capacitor should then be installed near the car audio amplifier. Keep the negative wire attached to the battery. Then, a ground wire from the negative post on the capacitor to the car's chassis on the chassis's bare metal ground point. Next, the power wire needs to be disconnected from the amplifier's power input. Connect the wire to the positive post on the capacitor. A new power wire needs to be connected from the capacitor's positive post to the amplifier's power input. Install a 16 gauge wire from the capacitor's remote turn-on post to the amplifier's remote input. Then disconnect the negative wire from the battery.
Can you run 4 gauge from your B to Capacitor then 8 gauge from the cap to the amp?
Now I'm guessing that while you have a 4 gauge input on the cap, you only have an 8 gauge input on your amp. So to answer your question, yes you can, but you will not draw as much power through the 8 gauge as you would the 4. Remember that the capacitor should be located as close to the amp as you can get it.
Why we get triangular wave as output when we apply square wave as input?
because of charging and discharging of capacitor present in the circuit. beacause capacitor charges exponentially. akshay dabhane

How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
