1Pew 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.
2ObjectivesUsing 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.
3Homework: Castle Learning – Review TEST !! - Tomorrow (Thursday!) (Friday if delay or snow day)- on all of Current Electricity (Packet)
4Finish Parallel Worksheet Homework ReviewGo through packet examples.ResistanceResistivityCurrentOhm’s LawPower LawSeries and Parallel CircuitsThen review questions.
5Try 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…
6Show 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…
7The diagram below shows currents in a segment of an electric circuit. What is the reading of ammeter A?
8The 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?
9Recallseries circuit – a circuit in which two or more elements are connected end-to-end so that a single loop of current is formed.
10Definitionsparallel circuit – a circuit in which two or more elements are connected so that each has its own current loop.
12Draw 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.
