Determine the current through the battery in the circuit shown in Fig
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
Sol. At the first moment after the connection of the key K, the capacitors are not charged, and hence the voltage between points A and B is zero (see Fig.)
The current in the circuit at this instant can be determined from the condition
I 1 = 
.
Under steady-state conditions, the current between points A and B will pass through the resistors R 1 and R 3 . Therefore, the current passing through these conductors after a long time is
I 2 = 
.
