93. A parallel circuit is one with several paths through which electricity can travel. The totalresistance in a parallel circuit is always less than the resistance in any single branch. The total1resistance R for the circuit shown can be computed from the formulawhereR2R1R1R2R and R, are the resistances in the individual branches. Suppose that a resistor with a fixedresistance of 6N (ohms) is placed in parallel with a variable resistor of resistance x.a. Write R as a function of x.b. Complete the table.Current6121830R(x)c. What value does R(x) approach as x→ 0? Discuss the significance of this result.
