Explain quantitatively why the maximum power transfer curve is not symmetrical about the point where the source resistance equals load resistance?

when we look at the curve ,, we can see that before the peak point curve has greater slope as compared to the slope after the peak point .. the reason is PL is given as I^2RL ,,, current is a squared term here . before peak point current is greater so overall change in power is much greater but after peak point RL is greater and current is less now the load resistance is not a squared term... so slope will be less. therefore the curve is not symetrical

Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
What is insulation megger draw and explain with neat diagram?
Meggar is a hand driven tool for measuring insulation resistance and earth resistance.
Use Ohm's Law and explain how 2 circuits have the same current but different resistance?
As we know V=IR, by changing the voltages in the two different circuits, we can maintain the same current even we have different resistance.
Is potentiometer and Thermistor are variable resistors. How please explain?
A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
Explain the relationship between voltage current and resistance?
The ratio of voltage to current is called resistance. In hydraulic terms, you can equate voltage to the difference in pressure between two points, current with the resulting flow of fluid between those points , and resistance as the opposition to that flow.

Explain why some plasmids contain a gene for resistance to an antibiotic?
Plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state. Plasmids may carry genes that provide resistance to naturally occurring antibiotics in a competitive environmental niche, or the proteins produced may act as toxins under similar circumstances.
Explain how water can transfer energy by conduction and by convection?
It cant. proven point
Explain three forms of resistance to western domination?
Essentially, resistance to Western domination means the rejection of the oppressor. This means Law, Military, Warfare & Morality.
Explain how changing the resistance in a circuit chages the current?
Ohms' law says if voltage stays constant resistance controls the current flow. Resistance goes up, current goes down. E/I*R.

Explain why air resistance is larger when the car is traveling faster?
Bikes cars and other moving objects experience air resistance as they move.Air resistance is caused by the frictional forces of the air against the vehicle. The faster the vehicle moves the bigger the air resistance becomes.
