How much current passes through the celling fan?

More information is needed to answer this question. Voltage, type of fan, horsepower of the fan or wattage of the fanareneeded to find what the current draw of the fan.


How do power cords differ?

Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.


How much output voltage is there if input voltage from a transformer is 32v?

It depends on the turns ratio of the transformer.


What circuits use capacitors?

there are infinite circuits that use capacitors however some common ones include: frequency filters: the capacitor is used in conjunction with a resistor to only allow either high or low frequencies to pass through the circuit. Time delay circuits: such as the intermittent setting on windscreen wippers. a capacitor is charged up and when it reaches a high enough voltage it is able to close a relay switch and start the wiper blades. Transient circuits: similar to above in usage, but is done by creating a "ringing" in the circuit. much like hitting a bell. once the ringing becomes quiet enough the circuit becomes active. this is used in automatic roller doors to keep the light on after the door has closed for 30 seconds or so. Voltage regulators: to maintain a steady voltage capacitors are used to "absorb" sudden spikes and troughs in the voltage input. much like suspension in a car absorbs vibrations when it hits a pothole.


Does the material of the diode depends on break down voltage?

A Germanium diode has a much lower breakdown voltage than a silicone diode.
