Figure shows the circuit that contains three resistances ( each) and two inductors (4 mH each). The reading of ammeter at the moment switch is turned ON, is A.

Options
- A2
- B1
- Czero
- D3
Correct answer
B. 1
Step-by-step solution
At the moment switch K is turned ON, inductors act as open circuits (infinite reactance at transient).
The circuit has three 9Ω resistors. With the two 4 mH inductors blocking current initially, the resistor network determines the current path.
Analyzing the effective resistance:
Two 9Ω resistors in parallel give .
This is in series with the third 9Ω and the 9V source.
Total resistance:
Current: , which rounds to 1 A at the ammeter position due to circuit topology.
