Name : Raghav Goyal Grade : IX B IGCSE Date : 25th October 2004 Physics Lab Report Electricity 3 (Parallel Circuits) Aim: To investigate if Kirchoff's 2nd law is true- "The total current I is equal to the sum of the currents distributed across the branches of the parallel circuit i.e. Total I = I1 + I2" Background information: Kirchoff's Law states that the source current is divided between the two resistors in parallel (according to the ratio depending on the resistance offered by each resistor). Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. This fact is true in both series and parallel circuits. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage. In a parallel circuit the source current divides among the available paths. In a parallel circuit (like the two examples...
