To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law isE=I⋅R, which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop. How is design current calcu...

导线截面积与载流量的计算(如何计算电缆平数)(Calculation of sectional area and Ampacity of conductors (how to calculate cable number)) In general, a copper wire carrying capacity of wire safe carrying capacity is based on the allowed core temperature, cooling conditions and installation conditions to...
The input force can vary between load, weight, tension, compression, or pressure, and it can only be measured by a sensor that is designed to calculate that type of force. (We will break down the different kinds of load cells/ force transducers in the section below.) Industries that use...

Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
Ask in tech support forums Q: What power supply wattage do I need for my upgrades? A: Calculate required wattage by: Adding up component power requirements Adding 20% overhead for efficiency Considering future upgrades Checking manufacturer recommendations ...
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 ...
When you connect a low ohm resistor in parallel with a circuit, the current flows through the shunt resistor -R- and generates a voltage drop. Typical shunt measurement hook-up in a simple circuit We can measure this drop and apply Ohm’s law to calculate the current. Graphical representat...
