How is gain measured on an amplifier?
How is gain measured on an amplifier? Amplifier gain is simply the ratio of the output divided-by the input. Gain has no units as its a ratio, but in Electronics it is commonly given the symbol “A”, for Amplification. Then the gain of an amplifier is simply calculated as the “output signal divided by the […]
What is the relationship between weight and speed?
What is the relationship between weight and speed? Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force. Is speed a weight? First of all, weight is […]
What is the difference between 4-20mA and 0 10V?
What is the difference between 4-20mA and 0 10V? Thank you for this question! 4-20mA is better for noise resistance (provided you run it properly in a shielded cable grounded at one end). 0-10V is better for troubleshooting. To troubleshoot a current loop, you have to have a multimeter capable for reading DC current in […]
What is the probability that a card randomly drawn from a standard deck of 52 cards is not a king?
What is the first law of thermodynamics and how does it relate to energy use?
What is the first law of thermodynamics and how does it relate to energy use? What is the first law of thermodynamics and how does it relate to energy use? The first law of thermodynamics states that energy is conserved in chemical processes. This amount of energy that must be lost to the surroundings for […]
What is uniaxial tensile test?
What is uniaxial tensile test? The uniaxial tension test is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (r-values). Tensile testing, monotonic to failure (i.e. ASTM D638, ISO 527 etc.) Why is it important to […]
How many atoms are centered on the 100 plane for the FCC crystal structure?
How many atoms are centered on the 100 plane for the FCC crystal structure? 4 atoms What are the 3 types of unit cells? A unit cell is the smallest repeating portion of a crystal lattice. Unit cells occur in many different varieties. As one example, the cubic crystal system is composed of three different […]
