Question

inr3,r4,r5 are30hm,6ohm,4ohm what is the effective resistance​

Answer 1

Answer:

First connect two 6 ohms resistors in series.So,the equivalent Resistance will be 12 ohms.Now connect this 12 ohm resistor in parallel with 6 ohm resistor…so the equivalent will be 12*6/12+6=72/18=4. So the equivalent is 4 ohms.that’s it.
