Homework:
LDR - when the light intensity increases, the resistance decreases, voltage across decreases.
LDR - when the light intensity decreases, the resistance increases, voltage across increases.
Thermister - when the temperature decreases, the resistance increases, voltage across increases.
Thermister - when the temperature increases, the resistance decreases, voltage across decreases.
Transistor - switch on when voltage is above 0.7 V.
Fuses - 3A fuse for < 690 W, 13 A fuse > 690 W
Parallel circuit - same voltage
Heat (energy) is lost to the surroundings
