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 size amp circuit breaker should be used for a geyser?
The size of the amp circuit breaker needed for a geyser will depend on the specific electrical requirements of the geyser. It is important to consult the geyser's manufacturer specifications to determine the appropriate amperage for the circuit breaker. Typically, a 20-amp circuit breaker is commonly used for residential geysers, but larger geysers may require a higher amperage circuit breaker. It is crucial to ensure that the circuit breaker is properly sized to prevent electrical hazards and ensure safe operation of the geyser.
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.
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
For circuit breaker what does it mean by AF AT?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
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.
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.
What size circuit breaker for a 1 ton air conditioner unit?
For a 1 ton air conditioner unit, the circuit breaker size typically ranges from 15 to 20 amps. The exact size needed will depend on the specific model and requirements of the air conditioner, so it is best to consult the manufacturer's specifications or an electrician to determine the appropriate circuit breaker size for your unit.

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 size wire do I need for my electrical project?
The size of wire you need for your electrical project depends on the amount of current the circuit will carry. Consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific project.
What factors determine the size of a current?
The size of a current is determined by the voltage applied, the resistance of the circuit, and Ohm's Law (current = voltage / resistance). The type of conductor material used, the temperature, and the cross-sectional area of the conductor also affect the size of a current.
What is the recommended wire size for a 30A circuit?
The recommended wire size for a 30A circuit is typically 10-gauge wire.
What is the recommended wire size for a 40A circuit?
The recommended wire size for a 40A circuit is typically 8-gauge wire.
