Energy Calculation Worksheet 2018 4. List the applications of Ohms law. A resistor with a high resistance rating (many ohms of resistance) will dissipate more heat power than a lower-valued resistor, given the same amount of electric current through it. Based on this principle, the sum of all power dissipations in a circuit must equal the total amount of power supplied by the energy source, regardless of how the components are connected together. WebWatts Law Solved Problems 1). Somehow, the power dissipated by the light bulb must be increased. Some students might not realize that in Europe, commas are used as decimal points and visa-versa.
