Power, Current and charge
1 When an electricity charge flows through a resistor, the resistor gets hot.
2 Energy has been transformed from electrical energy into heat energy
3 Power (watts, W) = Energy transferred/transformed (Joules, J) Time Taken (Seconds, S)
3.1 P=E T
4 Power (Watts, W) = Current (Amperes, A) x Potential difference (Volts, V)
4.1 P = I x V
5 This heating effect occurs in all types of resistance not just resistors
5.1 therefore the cables themselves and all electrical devices generate heat depending on their resistance
