An example of the calculation of chains with features.

Lecture



A special feature is the presence in the circuit of a branch with an ideal EMF

Given:
  An example of the calculation of chains with features.
R1 ÷ R5 = 10 Ohm, E1 = 30 V, E2 = 60 V

The current in any branch of the circuit can be found by the generalized Ohm's law. For this it is necessary to determine the potentials of the nodes of the circuit. Grounding any node of the circuit φс = 0, then the potential of the node b is equal to the value of E1 (if the EMF is directed to the node, then the EMF is taken with the “+” sign). In this scheme, we make one equation to determine the potential of node a.
When solving circuits with features, a node is grounded to which a branch is connected with an ideal EMF.

According to the generalized Ohm's law, we determine the currents in the branches.
