Energy, Power and Heat Mind Map

Energy, Power and Heat Mind Map

1. Ohm's Law

   • V= IR
   • I = V/R
   • R= V/I
   • states that the current through a conductor between two points is directly proportional to the potential difference across the two points.

2. Power and resistance

   • H = I^2R = V^2/R
   • Ac/ Dc

3. Heat

   • H = I^2Rt = Pt
   • a process of transfer of energy between a system and its surroundings other than by work or transfer of matter.

4. Kilowatt Hours

5. Power

   • P=IV
   • Power is the rate at which energy is generated or consumed and hence is measured in units (e.g. watts) that represent 'energy per unit time'

6. Watt

   • Unit of Power
   • one watt is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V).
