Explore the voltage and current at multiple points throughout a circuit using Kirchhoff's laws. Learn about conservation of electrical charge and why the total amount of current flowing into any circuit node will be equal to the current flowing out of it.
- [Narrator] Resistors don't have to be combined…in just series or in parallel.…Electronic components can be combined…in both series and parallel…to create some pretty complicated-looking circuits.…For example, this circuit consists…of two sets of parallel resistors…which are in series with each other.…To analyze a network of components like this one,…we use two handy equalities known as Kirchoff's Circuit Laws…which describe how voltage and current…are conserved throughout a circuit.…
Kirchoff's first law on current is used to understand…how the incoming and outgoing currents…relate to each other at a circuit node,…which is the junction where two or more components meet.…You can think of the circuit node…as the intersection between roadways.…And the current traveling through the components…are cars traveling along the roads.…Since we're not creating or destroying…electrons with our circuits,…we're just moving them around,…all of the cars that go into each intersection…must also come out.…According to Kirchoff's Current Law,…
