What is the length of the wire (in m) needed to achieve this? How does the gauge of a wire affect the induced emf in a coil of wire? How much heat is dissipated by the 1 ohm resistor? If the cross-sectional area of a piece of wire is halved, what happens to the resistance ...
Component placement, lead dress (wire length and placement) and power filtering all become more critical. Higher gain amps can take what would be an acceptable level of noise and amplify it to the point the amp is unusable. If you build a high gain kit amp you can expect to spend some ...
Nichrome wire has two features that make it a good producer of heat: It's a poor conductor of electricity compared to something like copper wire. This gives the alloy enough resistance to get hot from all of the current flowing into it. It doesn't oxidize when heated. Other metals like ...
After the soldering process is over, it is important to clean the board to remove any unwanted flux residue that can affect the performance of the board and can even cause electrical short circuit. No-clean flux doesn’t need any cleaning. In case of fluxes that need cleaning after ...
What type of elasticity is involved in the following cases? (a) A gas (b) A wire pulled at its ends (c) A liquid Relating to physics, describe an insulator. Explain why the voltage and resistance will change depending on the length of the material. Give the units of stress, strain ...
The inductance is formed by wrapping a wire around the core. If there are many turns, the resistance associated with the total wire length is significant. Since this resistance is in series between the half-bridge and the speaker, some of the output power will be dissipated in it. If the...
Cable Length Compensation (CLC™) technology from Miller eliminates these added steps and takes the guesswork out of addressing voltage drop — making it easier and more convenient for operators. As a result, operators stay under the hood longer, which improves the operation’s...
These tests detect ageing and premature deterioration of the insulating properties before they reach a level likely to cause the incidents described above. This test is often used as a customer acceptance test, with minimum insulation resistance per unit length often specified by the customer. The ...
Why is it necessary to measure the average resistance/unit length of the wire? How does an optical lever work? You are given a thread and a meter scale. How will you estimate the diameter of the thread? Why do telephone wires hang higher in winter than in summer? How does the flush ...
The LB should have added capacitance to create a filter to cancel out any noise that will be introduced by the length of wire from the loads to the LB, noise generated by the loads themselves and the length of wire used on the test leads. On most ATX set-ups, a low ESR 10uF cap ...
