If the electric potential is 220V and some device needs 1500watts then how does it suck exactly that amount of electrical energy from outlet?


Question: Solubility, pressure and Henry's law
Answer: Henry's law is given by the formula $p$=$K_h$$x$. Here $p$ is partial pressure of the gas $K_h$ is henry's constant for that gas and $x$ is mole fraction.Using this you can find it.
