Commutation process in RLC circuit

Click For Summary
SUMMARY

The discussion focuses on solving the commutation process in an RLC circuit, specifically determining the current flowing through E1 after E2 is connected. The participant struggles with the equations at time t=0, referencing the equation dUc/dt|t=0 = i3(0)/C. Key equations include L*di2/dt + Uc - R2*i6 + r1*i5 = E2 and Uc - R1*i5 = E1 - E2, indicating the relationships between current, voltage, and resistance in the circuit.

PREREQUISITES
  • Understanding of RLC circuit theory
  • Familiarity with differential equations in electrical engineering

Homework Statement



Still can't figure this one out.
All data is on the picture attached.
I have to find the current flowing through E1 after E2 is connected and draw a graph as it changes in time of the process.

I can't do the equations when t=0

Homework Equations


dUc/dt|t=0 =i3(0)/C


The Attempt at a Solution



t=0
i2-i5=i3+i6
L*di2/dt +Uc-R2*i6+r1*i5=E2
Uc-R1*i5=E1-E2
i still miss something, any help would be apritiated
