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.

In a DC circuit must the positive and negative conductors be the same size if not how is the size difference determined?
Yes, since the current is the same through out the complete circuit. the design size of the conductor entering the circuit should be the same size as the conductor leaving the circuit.
What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
Why are large transformers designed not to have optimum regulation in order for circuit breakers to be within reasonable size?
Transformer voltage regulation and size of the circuit breakers have no direct relation
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
How do you determine the proper fusing of a circuit?
Fusing is based on wire size and demand load.
How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
Which circuit breaker to use for the plugs and geysers?
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
In a DC circuit must the positive and negative conductors be the same size if not how is the size difference determined?
Yes, since the current is the same through out the complete circuit. the design size of the conductor entering the circuit should be the same size as the conductor leaving the circuit.
What should be the short circuit setting of the feeder breaker of a transformer so that it does not trip on short circuit fault in secondary side?
You need to model this - the line impedance and transformer impedance, and the voltage will determine this. There is no "one size fits all".
Advantages and disadvantages of IC rectifier?
Small size Low cost Low weight Easy Repalcement
What gauge wire do you need for 12 volts at 4.2 amps in my car for a light H11 Light bulb?
Almost any size wire will handle the 4.2 amps. BUT...as with any wiring, you must look at the over current device to determine the proper size. You need to determine which fuse in the fuse panel protects that circuit and use a wire that is appropriate for that size fuse.

What type of energy do electronics use?
Electronics circuits and devices are operate on D.C power supply. But the source of D.C power are mostly batteries and rectifiers. Batteries are really deliver pure D.C supply but they are bulkier and big in size. So we use rectifier circuit for operating Electronic devices. sometimes where backup of supply is needed there both source may present for example in laptops there batteries and rectifier(adapter) both are used.
What is the use of wire gauge?
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
What size fuse for 12v battery?
The fuse you use is determined by the load on the circuit and the size wiring used in that circuit not the battery voltage.
