A capacitor can act as a pacemaker by storing and releasing electrical energy in a controlled manner, mimicking the rhythmic electrical impulses generated by the heart's natural pacemaker cells. When charged, the capacitor discharges its stored energy at a specific rate, creating a pulse that can stimulate heart muscle contraction. This principle is utilized in electronic devices designed to regulate heart rhythms, helping to maintain a consistent heartbeat when the body's natural pacing is insufficient.
capacitor acts as resistor because it has some resistace alos.
reverse bias it
Most common use of a pacemaker is to have it help the heart keep its rhytm, but they can also be set up to act as a an integrated defibrillator to shock start the heart if it should stop.
The cutoff frequency of filter depends upon the value of capacitor and resistance. Therefore, below cutoff frequency or above this frequency, capacitor allow to pass all other frequencies.
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
pacemaker is a pacemaker
A: It is called discharging a capacitor. The charge will follow the rules of a time constant set up by the series resistor and the capacitor. 1 time constant 63% of the charge will be reached and continue at that rate.
the capacitor starts the compressor generally if it don t work the compressor usually won t start
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
Only in that it can store energy. However, the energy stored in a capacitor is usually very small, compared to a battery; and it can only hold the energy for a short time.
Capacitors have an equivalent reactance of 1/jwC (ohms) where w is the angular frequency of the AC signal and C is the capacitance. As the frequency of the signal across the capacitor increases, the capacitor reactance approaches 0 (capacitor acts like a short circuit). As the frequency of the signal across the capacitor decreases, the capacitor reactance approaches infinity (capacitor acts like an open circuit). So, if you have a high frequency signal (like a step input) the capacitor will momentarily act like a short.
A leaky capacitor will act like a load therefore decreasing the DC and increasing ripple eventually the capacitor it will self destruct because of heating probaly taking out the rectifiers as well.
