and the distance from the charge, r, is in meters. This formula tells you the strength of the electric field a certain distance away from the charge. When we look at this field strength, we can also draw a relationship to the electrical energy of this E field which can tell...
Impedance Definition: The total resistance generated by an alternating current flowing through a known frequency is called impedance (Zo). For PCB, the impedance of a signal layer to its adjacent reference layer under high frequency signals. 1. Main types of PCB impedance: (1)Single-ended impeda...
The method for calculating specific resistance of a single crystal comprises: a first step of calculating the amount of initially volatilized dopant (Eo) at an initial point in time immediately before the body of the ingot grows; a second step of calculating the amount of volatilized dopant ...
The core of the design and selection of tubular heat exchanger is to calculate the heat transfer area of the heat exchanger. To calculate the heat transfer area, it is necessary to know that K and Delta tm, K values are related to the structure, size and flow channel of the equipment. ...
How to Find Resultant Displacement in Physics How to Calculate the Total Magnitude of Displacement How to Calculate Contact Force How to Find the Magnitude When Force & Angle Is Given? How to Calculate Forces Acting on Beams How to Calculate a Change in Momentum ...
In the challenging physics field, one basic is the concept of speed and how it changes. Learning how to solve problems by finding the resultant velocity can be less challenging by keeping a few rules in mind. Knowing to calculate an object's speed makes

Rhs-conv, is the thermal resistance due to convection from the heat sink to the air inside the enclosure. 1 where: 2 3 4 The variable accounts for the decrease in temperature between the base of the heat sink and the tip of the fins since all the correlations used to calculate the ...
The formulas used to calculate BMR are different for men and women and they've been revised since they were originally created. These are the revised Harris-Benedict BMR equations: Male: (88.4 + 13.4 x weight in kilograms) + (4.8 x height in centimeters) – (5.68 x age) ...
A major drawback of using a voltage divider to calculate SOC is that it often produces inconsistent readings. A battery’s terminal voltage depends on the SOC as well as on load current, temperature, and age. Any variation in these three parameters can lead to ...
