Bell Work series circuits use your phet simulation

Bell Work: series circuits (use your phet simulation) 1. The ( current / voltage / resistance ) drop in each resistor add up to the total ( current / voltage / resistance ) supplied by the battery. 2. The ( current / voltage / resistance ) is the same everywhere. 3. There is ( one / multiple ) paths. 4. The ( current / voltage / resistance ) of all pieces in the circuit add up to the total (current / voltage / resistance ).

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.

Series circuit rules 1. Voltage adds up. 2. Current is the same everywhere. 3. Resistance adds up.

Let’s Practice! Practice #1 12 Ω RT = ______ 1 A IT = _______ 1 A I 1 = _______ 1 A I 2 = _______ V 1 = ______ 3 V V 3 = ______ 5 V

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.

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.

Let’s Practice! Practice #1 8Ω RT = ______ 2 A IT = _______ 16 V V 1 = _______ 16 V V 2 = _______ I 1 = ______ 1. 6 A I 2 = ______ 0. 4 A 16 V 10Ω 40Ω
