In the given figure switches S(1) and S(...

In the given figure switches `S_(1) and S_(2)` are in open condition. The resistance across ab when the switches `S_(1) and S_(2)` are closed is ……………… `Omega`.

Text Solution

Verified by Experts

The correct Answer is:
10
`R_(ab) = (12 xx 6)/(12 + 6) + (4 xx 4)/(4 + 4) + (6 xx 12)/(6 + 12) = 10 Omega`
