Slip ring commutator To use this e.m.f. to produce a current the coil must be connected to an external circuit using a split-ring commutator. Slip-rings lamp Transformers These are useful devices that can increase or decrease an applied voltage. They work on the principle of magnetic inducti...
phetioObjectMap['circuitConstructionKitDc.introScreen.model.circuit.vertexGroup.vertex_2'] I was able to see that vertex_2 doesn't exist in either the upstream or downstream simulation. Other vertices, such as vertex_4 do exist in both. So perhaps we need an earlier assertion that a ...
We addressed the problem in phetsims/circuit-construction-kit-common#999 and would like to republish with the fix. Please test to make sure you can see the problem on https://phet-io.colorado.edu/sims/circuit-construction-kit-dc/1.3/ and that you cannot see the problem in https://phet-...
