+the circit should work at night as, the ldr will dawf the other resistor
+
+the circit will not work at day as the ldr is still 400 OHM's which is
+higher than the 100 OHM resistor
+
+because the bulb has a resistance of 100 OHM's it will not work as expected
+
+this will cause the bulb to never be properly on as the resistance in the bulbs branch
+will limit the voltage through it to be <100 OHM's and thus it wont get 6V over it
+
+to fix this a voltage follower can be place between the bulb and the potential divider
+to keep the impedances at the right locations

+(see book for details)

+6)a)iii) when the switch is releases the voltage over the capacitor will be at 8.65 V
+this will mean the led is on.
+when it falls to 6V the capacitor will make the logic gate switch 3.34 seconds after the switch 
+is released, this will cause the not gate to switch and the led to be on
