~ 3 ~ I. Objective : Method : 1. The first thing we did was measured the voltage of the emf, or in this case, a 6 volt lead/acid battery (Figure D). We measured this by making sure the multimeter (figure A) was set up to read voltage, and touched the positive lead to the positive terminal of the battery and the negative lead to the negative terminal of the battery. We then recorded the results. 2. We calculated the relative uncertainty by taking the uncertainty given to us in class and divided it by the measured value. 3. The next step in our experiment was to set the resistor decade box (Figure B) to 1000Ω. We made sure to set the box to 1000Ω before hooking a power supply up in order to ensure a short was not produced. The power supply was hooked up by attaching lead wires in series to the decade resistor box. After setting the box, we set the multimeter (figure A) to read ohms used and touched the positive and negative leads to both the positive and negative terminals of the resistor box respectively. The results were recorded.

~ 4 ~ 4. Calculating the relative uncertainty was done the same way as step two, only using the uncertainty given for ohms. 5.
