SEPTEMBER 2010 UNIVERSITI TEKNOLOGI PETRONAS FAP0025: PHYSICS II DISCOVERY LEARNING Page 1 of 6 EXPERIMENT 1: OHM’S LAW LEARNING OUTCOMES: At the end of this experiment, students should be able to: Use Ohm’s law to determine the magnitudes of current and magnitudes of voltages in a circuit containing network of resistors arranged in parallel and series. Use the measured value of a wire’s resistance to determine its radius. THEORY Ohm’s Law state that current through a circuit is proportional to the applied voltage. This is symbolically written as: A plot I vs V should give a straight line passing through the origin, as shown in Figure 1. The slope of the line is R 1 . Figure 1: I-V Characteristic curve for a typical Ohmic material V=IR V= Voltage, R= Resistance, I= Current I (A) V (V)
