Question

13. Calculate net resistance of circuit and
current through 3 Ohm resistor.​

Answer 1

Answer:

When key K2 is closed, no current will pass through 2 and 3 ohm resistors, hence, all current will pass through 5 ohm. Hence, V across 5 ohm = 6 V = V across battery = reading of voltmeter. Now, this will distribute into two resistors of 5 ohm and 5 ohm. They both will get 2.4/2 = 1.2 A.
