1. Make a table to show your predicted resistance, actual resistance, and percent error for each of the 6 circuits. 1. Series circuit powered with 12 volts with 3.3 OHM, 100 OHM, 120 OHM and 220 OHM resisters. 2. Series circuit powered with unknown voltage uses 1 mA of current. The circuit contains 1k, 220, 15k and 3.3 OHM resistors. 3. Parallel circuit with 3 branches of resistors all powered with 7.5 volts. The first branch has a 1K OHM, 2nd branch has a 100 OHM, and 3rd branch has 220 OHM resistor. 4. Parallel circuit with 4 branches. The first branch has a 3.3 ohm resistor, 2nd branch has 120 ohm resistor, 3rd branch has 100 ohm resistor and the 4th branch has a 220 ohm resistor. There is an unknown voltage and the current is 500 mA. 5. Combination parallel and series circuit running on 18 volts. Branch 1 has a 100 and 120 ohm resistors in series. Branch 2 had 2 220 ohm resistors in series. Branch 3 has a 3.3 ohm and 1k resistor in series. 6. Combination parallel and series circuit running on an unknown voltage but using .230 amps. The first branch has a 120 ohm resistor, branch 2 has a 100 ohm resistor in parallel with a 220 OHM resistor. Branch 3 has a 3.3 ohm resistor in series with 1000 ohm and 15k resistors in parallel.
Make a table to show your predicted resistance, actual resistance, and percent error for each of the 6 circuits. Build and use an ohm meter to test each of the 6 circuits. Notes
