the current through the bulb 2.
Answer to Problem 30SSC
The current flowing through the bulb 2 is 0.6 A.
Explanation of Solution
Given:
Four resistors are connected.
The circuit diagram is
Formula used:
Kirchhoff’s law can be expressed as
Here,
Calculation:
Kirchhoff’s first rule states that the sum of incoming current towards a junction in a circuit is equal to the sum of outgoing current away from that junction.
The circuit diagram is as shown below
In the above circuit, 1,2 and 3 are the three bulbs.
Rearrange the equation (1) for
Substitute the values in equation (2)
Conclusion:
Hence, the current flowing through the bulb 2 is 0.6 A.
