Photoflash
Uses a Xenon tube in parallel with a capacitor
capacitors in the hand held variety of photo flash are charged slowly with some sort of battery and oscillator
when the capacitor is charged to 600V or so it is ready to discharge
there will be an ignition coil to ionize the Xe
when the Xe starts to completely ionize In a 1" long tube its resistance fall from near infinity to 1/2 Ohm
This is about 1200 Amps
those little cameras use #20 wire
the average current is well below 1 amp
to figure the wire size i^2 * R is not so significant
more easily approximated as I^2*t
you figure the amount of power with I^2*r and the amount of time
this times the mass of the wire tells you how long it will take for the wire to melt
witch is how fuses work
photoflash the wire made from Xenon molecular wt 54 takes a while to heat to 9000K or so and to take pictures we like the black body spectrum rather than the bright bands in the uv its very near sunlight
This takes about 1 millisecond
the flash tube for a ruby laser is usually krypton wt 32
this heats much faster the flash lasts for about a 1 Microsecond
this flash runs the ruby up to those higher energy levels then as a few discharge and trigger others
this happens in about 1Nanosecond
A short time
What else can I help you with?
What causes a single pin hole in a spot weld?
may be a short squeeze time and high current without slope
How short circuit current measure?
In shortg circuit current is infinitive.
What is the difference between the inrush current and the fault current?
Magnetizing inrush current has bigger 2nd harmonics compare to short circuit current. the second harmonics content is about >60% of fundamental harmonic. magnetizing inrush current happened when we energised the transformer, and short circuit current happened if there is a short circuit between different alive phase.
What is principle of Current transformer?
why does have to short-circuit secondary wire of current transformer ?
What term is used to describe current that can flow in a circuit as a result of an undesired short circuit?
Generically, it's an 'overcurrent'; specifically, it's a 'short-circuit current'.
What is meant by Current Account balance in short?
It is the balance that the bank shows that you have in your account at that time
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
Can a numerical relay give protevtion to over current over voltage and short circuit current at the same time?
Yes. Most microprocessor based relays that have both voltage and current inputs can provide overcurrent and over voltage protection simultaneously. Short circuit current is the same as overcurrent.
What is the effect of transformer impedance on short circuit current?
Short circuit current will increase a lot.
Why is current maximum when short circuited?
when its is short circuited there will not be any drop and hence the current will b maximum when its is short circuited there will not be any drop and hence the current will b maximum
Is short term debt the same as current liabilities?
Current liabilities are liabilities that are due within 12 months. Short term debt is a current liability. However, there are other current liabilities. For example, taxes payable, interest payable, wages payable, accounts payable. Therefore, short term debt is not the same as current liabilities. (Short term debt is a current liability, but not all current liabilities are short term debt.)
What is the effect on the current when a short circuit occurs?
The current increases.
What is the units for the short circuit current?
The unit for short circuit current is typically measured in amperes (A) or kiloamperes (kA). It represents the maximum current that can flow in a circuit under a short circuit condition.
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
What are Current liability?
Current liability is a liability that will be paid for in a short period of time, usually consisting of less than a year. Accounts payable are current liabilities, while notes payable are long term liabilities.
What causes a single pin hole in a spot weld?
may be a short squeeze time and high current without slope
Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
