How to calculate pressure drop--Part 2: the fundamentals of pumped water systems.(Tech Topics)Pelikan, Robert
where V is the voltage, measured in volts, I is the amount of current measured in amps or amperage and R is the resistance, measured in ohms. Resistors impede the electron flow within a circuit and, depending on their material, offer more resistance than others. The voltage in a circuit ...
Click-through rate (CTR)is the percentage of people who click through to your site from links within emails, social media ads, or search ads compared to the total number of people who saw the ad. How to Calculate Click-Through The CTR formula varies slightly depending on the channel: Fore...

How to Calculate the Loan-to-Value Ratio Interested homebuyers can easily calculate the LTV ratio of a home. This is the formula: LTVratio=MAAPVwhere:MA=Mortgage AmountAPV=Appraised Property Value\begin{aligned} <V ratio=\frac{MA}{APV}\\ &\textbf{where:}\\ &MA = \text{Mortgage Amount...
This does a scan count of 44–once through the table to pick up the rows for EmployeeID 9, and then 43 more times to calculate the sequence number, once for every row in the result set. But it gets worse: 4,007 logical reads. Wouldn't it be nice to ease the burden on ...
It is critical to determine the optimum value for the current-sense resistor (RSENSE). Larger RSENSEvalues increase the series IR voltage drop and power loss; however, this would also minimize the effect of the offset voltage error, as shown in Table 2. For designs that ma...

This voltage difference between the cathode and control grid is called tube 'bias.' Common cathode tubes use the voltage drop across a cathode resistor placed between the cathode and ground to generate the bias voltage. The much more powerful 5E3P amplifier shown below uses an "adjustable fixed...
The electrical circuit model described in the previous section can be used to calculate the E-Field in the culture medium for a cylindrical geometry and a sinusoidal applied voltage. The described equations can be easily implemented in Excel, Matlab or Python, for example. When the waveform is ...
