Figure3. (a) Three capacitors are connected in parallel. Each capacitor is connected directly to the battery.(b) The charge on the equivalent capacitor is the sum of the charges on the individual capacitors.(3) Other related calculation formulasWhen the capacitor is connected in parallel, the...
Many empirical frequency distributions have the following characteristics: They are approximately symmetrical, and the mode is close to the center of the distribution. The shape of the distribution can be approximated by a bell: nearly flat on top, then decreasing more quickly, then decreasing more...
In the present study, we propose empirical formulas concerning heat transfer and pressure loss characteristics for pin-fin arrays, which are made of thin pins of square cross section arranged in a rectangular form. The effect of the pin pitches in the flow direction and transverse direction wer...

Firstly, the cross-sectional area of track is calculated. The copper foil thickness of most PCB is 35um (if you are not sure, you can ask the PCB manufacturer). The cross-sectional area is multiplied by the width of the line. There is an empirical value of current density of 15 to ...
There was a time when theoretical and empirical evidence seemed to suggest that conventional financial theories were reasonably successful at predicting and explaining certain types of economic events. Academics in the financial and economic realms nonetheless detected anomalies and behaviors that occurred in...
