First we made a normal
size house
• We measured the voltage with the switch off:
It was 2.8 V
• We measured the voltage with the switch on:
It was 2.1 V
Voltage of battery
Lamp circuit power
• The current of the lamp was 0.19 A.
• The circuit power was 0.4 W.
Then we made a super
house
Battery internal
resistance
• We then measured the circuit current:
It was 1.53 A
• Then we measured the battery voltage:
It was 2.6 V
Resistance
• We measured the resistance for one lamp:
It was 11.05 Ω
• Then for both lamps:
It was 6.05 Ω
How we worked together
• We split into two groups one group working on the
normal sized house the other working on the super house
