Group 5

Sigurgeir, Emi, Daniel, Sarah, Larisa, Jess,

Mario.

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
