Kdr determination: Pyrethroid resistance is correlated with the presence of the kdr mutation, that is, the presence of a T (kdr allele) instead of C (kds allele) at position 322 of the partial cDNA sequence of the para-like gene of M. persicae (Martinez-Torres et al, 1999). A PCR ...
How to calculate effective resistance. How does Newton's second law of motion show the relationship (increase or decrease) between gravitational force, mass, and free-falling acceleration in a free-falling object (negligible of air resistance and the drag force being air)? How does increasing the...
98K What is electrical resistance? Learn the meaning and formula of electrical resistance with examples. Understand the factors on which the resistance depends. Related to this QuestionWhat affects the resistivity of a wire? Why do semiconductors increase in conductivity with temperature? ...
Hi, I'm using a current sense amplifier chip due to the low resistance of the shunt (30mΩ). I'm viewing the output voltage of the amplifier with a multimeter. +1 vote by wcnola August 16, 2020 Interesting. It sounds like the current sense amplifier may not be working as intended...

As we know, a resistor is a passive electrical element that provides electrical resistance to the flow of current. Thus, according to ohm’s law, it will create a voltage drop when the current passes through a resistor. Mathematically, voltage drop across a resistor can be expressed as, ...
The article cites a study which does not support the concept that increasing breathing resistance causes an increase in respirator facial leakage. Increase in faceseal leakage with increasing pressure drop was not exhibited by respirators that met the Occupational Safety and Health Administration ...
Excess voltage increases internal resistance in the battery. Adding heat to this can cause an explosion. Reduced capacity. When there is too much heat, the internal reaction increases, causing a massive clash between the internal components. When the gases released interact, your battery may lose ...
Because I saw that the NMOS of this model only enters the constant resistance region when its ID reaches about 40A, as shown in the following figure. If that's the case, I would consider using electronic loads to increase the current load. Like 191 0 1 harshagovind Moderator 2...
Does resistance depend on temperature? Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, theresistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "...
