Guyton and Hall defined a vector as "A vector is an arrow that points in the direction of the electrical potential generated by the current flow, with the arrowhead in the positive direction. Also, by convention, the length of the arrow is drawn proportional to the vol...
How do we measure electrical force? A joule is equal to one what times one meter? A listener increases his distance from a sound source by a factor of 3.57. Assuming that the source emits sound uniformly in all directions, what is the change...
aA stereo sends an electrical signal to a speaker to produce sound. To digitize the signal we periodically measure the voltage of the signal and record the appropriate numeric value. 立体音响寄发一个电信号到报告人到产物声音。 要数字化信号我们周期性地测量信号的电压并且记录适当的数值。[translate]...
To detect potential battery cell defects at the earliest possible stage, in line with Regulation 100, fire suppression systems can be used as an additional safety measure, releasing a cooling agent to minimize fire risk. There are new and individual challenges to overcome and new risk asse...
Potential Flaws During testing, we noted this smart scale's readings were slightly inconsistent with standard scale readings. Still, we were impressed by how functional its app was. Most Valuable Insight "I like that I can see different body trends each day I weigh myself. You can also add...
A Better Way to Measure The tough part of the problem here is getting at reliable data. Just yesterday we sawan incredible resource monitoring projectthat uses an optical sensor to measure the turning or the wheel in an electric meter. We’ve seen similar projects for meters that have a blin...
utilization of mercury electrodes makes this method less desirable due to safety and environmental concerns. In nickel-plating solutions, concentrations of copper are high enough that it would be more appropriate to measure copper with a solid electrode. Mercury electrodes are more sensitive than solid...
