Introduction A resistor represents a particular amount of resistance in a circuit. Resistivity is the level of ability a material has to resist the flow of an electric current. Resistance has an effect on the voltage and current. Voltage is electrical potential per unit charge. Voltage is measured in joules per coulomb, or volts Procedure For this lab I followed instructions and studied the motion simulation for several minutes. Procedure Part I Wire Resistance:Open the PhET Simulation Electricity, Magnets, and Circuits Resistance in a Wire.As wire length (cm) increases, the resistance (Ω) __increases_______________As wire area (cm2) increases, the resistance (Ω) __________decreases________As wire resistivity (Ωcm) increases, the resistance (Ω) _____increases__________Procedure Part II: Ohm’s Law: Electricity, Magnets, and Circuits Ohm’s LawmA is milliamps, and ____100_____ milliamps equals one Ampere.•Move the potential (volts) and resistance (ohms) sliders and observe the current (amps)As voltage increases, current _______increases___________.
