What do we know about parallel circuits- Total current is equal to sum of the current in the individual branches IT = I1 + I2Component of each branch of a circuit share the same voltage as the cell V1 = V2 = VTUsing ohms law V=IR, 1/RT = 1/R1 + 1/R2 What do we know about a series circuit -Current has the same value at any point in the circuit IT = I1 = I2Emf of the cell is equal to the sum of the potential difference across each resistor V1 + V2 = VTUsing Ohm's Law V = IR, RT = R1 + R2 Draw a diagram to help us understand how current and voltage vary in circuitsCalculate effective resistance -For series 12 + 12 = 24 ohmsFor parallel 1/12 + 1/12 = 1/ R where R = 6 ohmsMake sure ans is given in correct unitsReflect on question - what was the issue? Why were you not able to ans the q? What did you forget?
