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) \(\frac { 1 } { R } = \frac { 1 } { R _ { 1 } R _ { 2 } }\)
