Energy, Power and Heat Mind Map
- 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.
- V= IR
- Power and resistance
- H = I^2R = V^2/R
- Ac/ Dc
- H = I^2R = V^2/R
- 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.
- H = I^2Rt = Pt
- Kilowatt Hours
- 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'
- P=IV
- 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).
- Unit of Power
