In an Electric Circuit, Two Resistors (Of Resistance R₁ and R₂

question 123

Essay

In an electric circuit, two resistors (of resistance R₁ and R₂, respectively)are connected so that the combined resistance of the circuit, R, is given by $\frac { 1 } { R } = \frac { 1 } { R _ { 1 } } + \frac { 1 } { R _ { 2 } }$ Find $\frac { \partial R } { \partial R _ { 1 } }$ .
