Question

calculate the combined resistences of three resistences 4 omega, 6 omega and 8 omega in series​

Answer 1

Answer:

Explanation:

To get an equivalent resistance of 6 ohms, we have to use both parallel and series connection in the circuit. First, the two resistors are connected in parallel to obtain a combined resistance of 2 ohms and then the combined resistance in connected in series with the third resistor to give a total resistance of 6 ohms.

That is, for the two resistors in parallel the resistance is given as   4

1 + 4 1  =  0.5 1

​  

=2ohms and this is added with the resistance of the third resistor in series as 2+4=6 ohms.
