Calculate the Resistance (Ω) of an appliance connected to a 60 V Source which has a Current of 9 A: Vocabulary: Combination Circuit – This is a circuit composed of ___________ and _____________ paths. Video Demonstration – Electric vs. Petrol Cars Electric vs. Petrol Car. Which would YOU use and why? _______________________________________________ ______________ In Petrol cars, the ________ tank and the I.C. Engine help to move the pistons in a linear motion. In an electric car, the power source is from a _____________ pack., Instruction- Combination Circuits Finding the Total Resistance in a Combination Circuit - The strategy is to focus on the equivalent resistance of ________ paths in order to transform into a series circuit. Combination Circuits - Instruction - Calculate the Total Resistance, then Use to calculate the Total Current. VT = IT = RT = Combination Circuits – Guided Practice – Calculate the Total Resistance, then Use to calculate the Total Current. VT = IT = RT = Combination Circuits – Check for Understanding - Calculate the Total Resistance, then Use to calculate the Total Current. 1. VT = IT = RT = 2. VT = IT = RT = 3. VT = IT = RT =
