How can you implement darlington pair using mosfet?
its not too hard... darlington transistors are simply a pair of bipolar transistors which allow for control of a significantly greater current or voltage (or both) via a low power signal such as a microcontroller. Frequently Transistors that can control a larger current or voltage require a higher gate voltage (Vgs) to fully turn on the transistor than the microcontroller is able to deliver so a smaller transistor is used to boost the control signal. You can build your own darlington out of a pair of bipolars - one that runs at logic level and boosts the signal to control the second one that runs at the higher current & voltage of the end device. The same can be done with mosfets. There are a fair number of mosfets that can control a decent current and voltage but in many cases you'll need to use either discrete boost (charge pump) mosfets, or a control chip that has built in charge pump circuitry. This is a fairly common requirement in building motor controllers and amplifiers which are or can be controlled by PWM or some other form of logic level signal. The international rectifier IR2104 is a good example of logic level mosfet that can be paired with a more powerful mosfet such as IRF540N for the actual current control. As mentioned you can also use a driver circuit such as those found in the HIP408x series which will obviate the need for a boost mosfet - this configuration is found in a number of commercial motor controllers including those by numerous wheelchair manufacturers.
What is telestimulation?
Telestimulation systems are described for chronic indirect muscle stimulation in caged rabbits and mice. Both system use a 5 MHz carrier frequency transmission and consist of a transmitter and a receiver. The latter is fixed to the back of the animal.
What does a capacitor store if the sum of charges of both capacitors is zero?
it may consist much of negative and positive chargeAnswerA capacitor stores energy within an electric field set up between its plates. It does not 'store' charage, as the net charge is the same both before and after the capacitor has been 'charged' (unfortunate use of the word!). What it does is to enable charge to be separated, with one plate then becoming negative with respect to the other, resulting in an electric field between the two plates.When we describe the 'amount of charge' on a capacitor, by convention, we mean the amount of negative charge stored on its negative plate, and not the sum of this and the amount of positive charge on its positive plate!
What is meant by unity coupled transformers?
The windings are wound as a pair, two wires next to each other. Same start point and same end point. In parallel, another words. They both share the same axis point also so the EMF is balanced as near to perfect as possible. The share the same EMF path when the electrons are changed into magnetism and then back to electrical current, hopping from the primary to secondary windings.

When exercising to build muscular strength why is it important to exercise both muscles in a pair equally?
It is important because both muscle's are a pair, So they should both be exercised in a pair for the equal amount of strength in both muscles.

The United States and the United Kingdom are both in stages of demographic transition. For both countries, an influx of immigrants have changed the culture.
How is telophase the reversal of prophase?
The prophase stage and the telophase stage of the cell cycle are similar in two ways. During both stages, cells have a complete set of chromosomes and organelles.
