Problem

Three resistors of

6\,\Omega

9\,\Omega

and

18\,\Omega

are connected such that the

6\,\Omega

and

9\,\Omega

resistors are in parallel, and this parallel arrangement is connected in series with the

18\,\Omega

resistor across a

36\,\text{V}

battery. a. (i) Draw a simplified circuit step by step to show how the network can be reduced to a single equivalent resistor. b. (ii) Calculate the equivalent resistance of the entire circuit. c. (iii) Determine the current supplied by the battery. d. (iv) Find the current through each of the

6\,\Omega

and

9\,\Omega

resistors. e. (v) Compute the electrical power dissipated in the

18\,\Omega

resistor.
