Adding a resistor to a circuit does not always decrease the current in the circuit. Depending on how you add a resistor to a circuit, adding a resistor can increase the total current in the circuit, and/or increase the current in one part of the circuit. Consider the circuit shown below. 4.0 2 18 V 3.0 2 6.0 2 (a) How would you add a resistor with a resistance of 9.00 2 to the circuit so that the current through the 3.0 2 resistor is maximized? O Put the new resistor in series with the 4 2 resistor. O Put the new resistor in parallel with the battery. O Put the new resistor in parallel with the 4 2 resistor. O Put the new resistor in series with the 6 2 resistor. O Put the new resistor in parallel with the 3 and 6 2 resistors. O Put the new resistor in series with the 3 2 resistor. (b) By how much does the current through the 3.0 2 resistor increase when you do that? The current increases by 0.543 X A.
