What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.
What converts an alternating current to diredt current?
Alternating Current can be converted to Direct Current by using a DC Converter which contain a Bridge Circuit , a Capacitor and if needed a Transformer.CommentA 'DC converter' is normally called a rectifier.
What will happen if two terminals of capacitor are shorted?
When the terminals of a capacitor are connected together, the capacitor will discharge, returning to a zero potential state. Capacitors resist voltage change, meaning that if the capacitor is in a circuit that has zero voltage potential, the capacitor will eventually achieve zero potential. If the capacitor is in a circuit that has a 5 volt potential, the capacitor will seek and attempt to maintain that 5 volt potential (provided that the capacitor is rated at 5 volts or more). In an AC circuit, the capacitor will tend to smooth out the sin wave of the current, resisting change in both directions. In a DC power supply circuit, a capacitor will tend to reduce the voltage "ripple", and if the circuit is designed properly, will provide a smooth DC voltage. Shorting the terminals of a capacitor is effectively what often happens in many circuits; it's not a problem.
Significance of the ripple voltage on a rectifier circuit?
A: It really depends on the load requirement . Example driving a relay hi ripple with no capacitor is an advantage in efficiency for a sensitive amplifier it will cause mayhem with the performance
A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
Why capacitor used in rectifier circuit?
To smooth the output of the pulsating DC.
What circuit is to be added to a full wave rectifier to produce a smooth DC?
put capacitor parallel on load (peak rectifier) or add low frequency pass filter (composed of L & C) to remove AC components
What is the advantage of full wave capacitor rectifier circuit?
to get maximum dc output
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.
What is the equivalent resistance of the parallel circuit you have connected?

A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
Why capacitor is connected to earth in circuit?
A capacitor is connected to earth in a circuit to provide a reference point for voltage levels. It helps in reducing noise or interference in the circuit by providing a path to ground for stray signals.Connecting the capacitor to earth also helps in stabilizing the voltage levels in the circuit.
Why capacitor is used in circuit board?
use as coupling in some circuts and and as a filter in rectifier circuit. use as DC current blocking.
What are the differences between a parallel circuit and a series circuit?
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
What ia series circuit?
A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
What is a rectifier with a single capacitor filter suitable to supply?
A circuit that doesn't require a lot of filtering such as a charging circuit for a battery. In a single capacitor filter, the sine wave or AC doesn't get completely eliminated.
