Mathematically it is given as. Where, I is the current flowing through the diode. What is the difference between pn junction diode and solar cell? The solar cell […]
How do you calculate the maximum efficiency of a heat engine?
How do you calculate the maximum efficiency of a heat engine? The maximum theoretical efficiency of a heat engine (which no engine ever attains) is equal to the temperature difference between the hot and cold ends divided by the temperature at the hot end, each expressed in absolute temperature (Kelvin). What is the maximum efficiency […]
Which property will be the same no matter how much matter is present?
How much time does it take to charge a capacitor?
How much time does it take to charge a capacitor? If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is […]
How does a Rankine cycle work?
How does a Rankine cycle work? The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work. […]

Is R410A going to be phased out?
Is R410A going to be phased out? All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. But it’s not so much the air conditioning […]
