Unformatted text preview: for several resistors and recorded the data as seen below. Resistance (Ohms) Current (Amps) Calculated voltage (volts) Votage (3V batteryl)/ resistance 1000 3.08mA 3.08 0.003 10000 .31mA 3.1 0.0003 100000 .031mA 3.1 0.00003 120000 .0259mA 3.108V 0.000025 560000 .0053mA 2.968V 0.0000054 1000000 .0003mA 3.1V 0.000003 1000000 .00003 3V 0.0000003 Analysis: By taking the known voltage and dividing it by the known resistance we found that our measured current was very close to the actual current. We were off my a few thousands of a Amp. Because of this we concluded that Ohms law is in fact true. Our errors could have been the result of a battery that was not fully charged or if our resitors were not perfect. Also our circuit may have been not perfect. Anyone or all of these may have contributed to non perfect results....
