## Electric Heat

Heat energy dissipated into the surrounding from the resistor. In any electric circuit, heat energy dissispated is considered as electric energy loss

### Electric Heat Energy

In an electric circuit of a voltage source and a conductor that possess a resistanc R, heat energy dissispated through resistor's resistance

${\displaystyle P_{R}=I^{2}R(T)={\frac {V^{2}}{R(T)}}}$

### Resistance change with temperature

${\displaystyle R(T)=R_{o}+nT}$ for conductor
${\displaystyle R(T)=R_{o}e^{nT}}$ for semi conductor respectively
