Ohm`s Law
... In this laboratory Ohm’s Law will be studied. Ohm’s Law states that the voltage drop across an electrical component of resistance R that has a current I through it is given by V=IR. In this lab current will be varied through a resistor R, and the resulting voltage drop will be measured across the re ...

Output resistance of a power supply
... current I. 1) Use the cell battery as power supply. Note that a small Rl means a large current, which drains the battery quickly. Plot V vs. I, calculate the output resistance of the battery Rb. Estimate the uncertainties. 2) Use the DC regulated power supply, set to the same value of V as that of ...
