Tutorial on using a multimeter Part B Color Code Value Meter Value Meter Units Meter Scale 1000 ohms 1.002 K ohms 2k 1500 ohms 1.487 K ohms 2k 5600 ohms 5.53 K ohms 20k 470000 ohms .464 M ohms 2M 10000 ohms 9.85 K ohms 20k 560 ohms 0.557 K ohms 2k Part C Point 1 Point 2 V 12 (V) A D 1.454 D A -1.452 B A -0.001 C B -1.452 9. From point A to point B the potential difference is nearly 0. This is because there is no resistance in the current from point A to point B, thus the voltage at the two points should be the same and their difference should be 0. 10. The potential difference V CB is negative because the voltage at point C is less than

Unformatted text preview: the voltage at point B. This is because point C is past the resistor and point B hasn’t passed though the resistor yet. Thus, when you subtract a greater voltage from a smaller voltage, the potential difference is negative. Part D Point Current I (ma) Current I (A) P 2.52 .00252 Q 2.54 .00254 14. The black probe was connected closest to negative terminal of the battery. 15. The current at points P and Q are almost the same because current is the same throughout the circuit....
