Optimizing Camera Flash Performance: The Role of RC Circuits An RC circuit in a camera flash is a type of electrical circuit that uses a resistor (R) and a capacitor (C) to control the flow of current and produce a flash of light in a camera The resistor limits the amount of current flowing through the circuit, while the capacitor stores and releases electrical energy to produce the flash 2
How to calculate flash point of mixture? - Physics Forums Flash Mixture Point In summary, the individual flash points of 53ºF for isopropyl alcohol and 142ºF for aliphatic hydrocarbon mixture can be raised by adding water to the alcohol and using higher alcohols to improve miscibility and flash point A precise calculation involving thermodynamics may be necessary for accurate results Jun 7, 2012
Macromedia flash Professional 8 loaders and scroll panes help To add a scroll pane, first create a new layer in your flash project and then select the "New Scroll Pane" option under the "Insert" menu This will create a new scroll pane object that you can then customize by changing the size, color, and scroll speed 4
Strange white flash in a dark room - II - Physics Forums The most likely explanation for a strange white flash in a dark room is a phenomenon known as phosphene This occurs when the retina of the eye is stimulated by pressure or electrical signals, causing a perception of light even in the absence of external light sources 2
Calculating Energy Transferred in Lightning Flashes Thunderstorms N = 1800 0278 = 64,800 for the number of storms taking place Now if you take energy flash = 4 * 10E9 J found in part (a) With 180 sec per flash then the average current is 4 * 10E9 J 180 sec = 2 2 * 10E7 amps for N storms Dividing by 1800 gives 2 2 * 10E7 1800 = 12,200 storms, approximately the given answer
Saving to Flash Drive: Copy Files Drives? - Physics Forums First, insert the flash drive into your computer's USB port Then, open the folder or location where the files you want to save are located Select the files you want to save, right-click and choose "Copy " Next, open the flash drive folder, right-click and choose "Paste "
Flash MX vs. 2004: Comparing Features and User Experience - Physics Forums Both Flash MX and Flash 2004 have similar animation capabilities However, Flash 2004 has more advanced features, such as motion tweening, which allow for smoother and more complex animations So, Flash 2004 may be considered better for creating animations 5
Find Capacitance for Camera Flash Unit - Physics Forums Jun 16, 2009 Capacitance In summary, the flash unit in a camera uses a special circuit to charge a capacitor to 300 V, which is then discharged through a flashlamp in 12 μs with an average power dissipation of 12 W Using the equations for energy and energy stored in a capacitor, the capacitance of the capacitor can be found to be 3 2*10-9 F
