WebV = J C. 19.48. We can rewrite this equation as J = V × C and substitute this into the equation for watts to get. W = J s = V × C s = V × C s. But a Coulomb per second (C/s) is an electric current, which we can see from the definition of electric current, I = Δ Q Δ t, where Δ Q is the charge in coulombs and Δ t is time in seconds. WebThe formula or equation of Joule ’ s law of heating is as follows Where, – Heat generated (Here it is in calories, cal) – Current passed (amperes, A) – Resistance of the wire (ohm, …
WebThere are two main ways that heat capacity is reported. The specific heat capacity (also called specific heat), represented by the symbol \text c c or \text C C, is how much energy is needed to increase the temperature of … WebThe formula is heat produced = voltage squared divided by resistance. In the question he found out the heat as 4 joule per second and then as given voltage was equal to 2 volts. Simply apply the formula. And of course, we can also substitute I equals V over R. Again, Ohm's Law, and …
WebThe amount of heat produced by the heater is calculated as follows: Q=I 2 RT substituting the values in the equation, we get Q = 10 2 × 300 × 30 × 60 = 54000000 J or 54 MJ. To know more about Joule’s law of … WebApr 8, 2024 · The heat energy of an electric appliance is generated due to the friction of electrons with the resisting elements. Heat is produced in our body due to the chemical and biological reactions that occur within the cells. Heat is also produced due to the vibration of the molecules or atoms.
