Investigating resistors Aim: * EM-5: to investigate the effect of potential difference on current in a carbon resistor * EM-6: to investigate how the addition of resistors in parallel or series affects the voltage and current in a circuit * EM-7: To determine the total effective resistance of a combination of resistors in series and parallel * From all EM-5, EM-6 and EM-7 are aimed to compare the results collected from the data (current and potential difference) Hypothesis: When we put all resistors together in series it will has greater effectiveness than in parllel because circuit all resistors will have same current but they will have different voltage. In parallel, resistors will have same voltage but different in current. In total series (R1+R2+R3) and in total parallel (). To calculate voltage = current (I) vs resistance (R) Variables: Dependent Independent Controlled Voltage and current in each resistors Resistors Amperemeter and voltmeter used Potential difference in each resistors measured by using voltmeter Number of resistors...
