To Find the Equivalent Resistance of the Combination of Resistors

question 55

Multiple Choice

To find the equivalent resistance of the combination of resistors shown below by the method of possibly repeated applications of combining resistors in series and /or combining resistors in parallel,the first step would be which of the following?

• A)Combine the 6.0 W and the 7.0 W in series.
• B)Combine either the 4.0 W and the 10.0 W in parallel or the 7.0 W and the 10.0 W in parallel first,since either could be the first step with the other the second step.
• C)Combine the 4.0 W and the 10.0 W in series.
• D)Combine the 6.0 W,the 4.0 W,and the 10.0 W in series in a single step.
