Add the Fractions on the Right Side of the Equals $$\frac { 1 } { R } = \frac { 1 } { R _ { 1 } } + \frac { 1 } { R _ { 2 } }$$

Multiple Choice

Add the fractions on the right side of the equals sign to obtain a single fraction for the application formula. Assume there are no zero denominators. Resistors in parallel in an electrical circuit: $$\frac { 1 } { R } = \frac { 1 } { R _ { 1 } } + \frac { 1 } { R _ { 2 } }$$

A) $\frac { 1 } { R } = \frac { 1 } { R _ { 1 } + R _ { 2 } }$
B) $\frac { 1 } { R } = \frac { R _ { 2 } + 1 } { R _ { 1 } R _ { 2 } }$
C) $\frac { 1 } { R } = \frac { R _ { 2 } + R _ { 1 } } { R _ { 1 } R _ { 2 } }$
D) $\frac { 1 } { R } = \frac { 1 + R _ { 1 } } { R _ { 1 } R _ { 2 } }$
E) $\frac { 1 } { R } = \frac { 1 } { R _ { 1 } R _ { 2 } }$
