Bell Work: series circuits (use your phet simulation)
The ( current / voltage / resistance ) drop in each resistor add up to the total ( current / voltage / resistance ) supplied by the battery. The ( current / voltage / resistance ) is the same everywhere. There is ( one / multiple ) paths. The ( current / voltage / resistance ) of all pieces in the circuit add up to the total (current / voltage / resistance ).
2
Solving Series Circuits
Either use Ohm’s law or the series circuit rules. Ohm’s law must be applied for the entire circuit (total) or at one resistor.
3
Series circuit rules 1. Voltage adds up.
2. Current is the same everywhere. 3. Resistance adds up.
4
Let’s Practice! Practice #1 RT = ______ IT = _______ I1 = _______ I2 = _______ V1 = ______ V3 = ______ 12 Ω 1 A 1A 3 V 5 V
5
Practice #2 15 Ω 3 A 9 V 12 V RT = ______ IT = _______ I2 = _______ I5 = _______ V3 = ______ V4 = ______
6
Solving Parallel Circuits
Either use Ohm’s law or the parallel circuit rules. Ohm’s law must be applied for the entire circuit (total) or at one resistor.
7
Parallel circuit rules
1. Voltage drop at each resistor is the same as what is supplied by the charge pump. 2. Current in the paths add up. 3. Inverse of resistances add up.
8
Let’s Practice! Practice #1 RT = ______ IT = _______ V1 = _______ V2 = _______ I1 = ______ I2 = ______ 8 Ω 2 A 16 V 1.6 A 0.4 A 16V 10Ω 40Ω
9
Practice #2 4.8 Ω 5 A 24 V 0.8 A 0.6 A RT = ______ IT = _______ V2 = _______ V3 = _______ I3 = ______ I4 = ______
