1 Pew PowThink about the differences between a series circuit and a parallel circuit and explain which method is used to wire your house. Show a formula and give a good reason why you believe this to be true.
2 ObjectivesUsing our knowledge of Ohm’s Law and the Power Law, practice with Series Circuits !Now apply our physics understanding to solve parallel circuits for things like voltage, current and resistance.
3 Homework: Castle Learning – Review TEST !! - Tomorrow (Thursday!) (Friday if delay or snow day)- on all of Current Electricity (Packet)
4 Finish Parallel Worksheet Homework ReviewGo through packet examples.ResistanceResistivityCurrentOhm’s LawPower LawSeries and Parallel CircuitsThen review questions.
5 Try this: (show all units!) The current in a wire is 8.0 amperes. The time required for 2.5 × 1019 electrons to pass a certain point in the wire is…
6 Show all workAn electric dryer consumes 6.0 × 106 joules of electrical energy when operating at 220 volts for 1.8 × 103 seconds. During operation, the dryer draws a current of…
7 The diagram below shows currents in a segment of an electric circuit. What is the reading of ammeter A?
8 The following resistors are placed in parallel: 10 ohms, 15 ohms, 6 ohms and 20 ohms. Draw the circuit and show how you would measure the current through the 15 ohm resistor. These are connected to a 120V power source. What is the equivalent resistance?
9 Recallseries circuit – a circuit in which two or more elements are connected end-to-end so that a single loop of current is formed.
10 Definitionsparallel circuit – a circuit in which two or more elements are connected so that each has its own current loop.
12 Draw a series circuit out of a 50 ohm resistor and a 100 ohm resistor and a 200 ohm resistor and a 20V battery. What is the current through the 100 ohm resistor?What is the voltage drop across the 200 ohm resistor?Now do the same thing but make a parallel circuit.
