When Two Resistors of Resistances $R _ { 1 }$ And $R _ { 2 }$

question 39

Multiple Choice

When two resistors of resistances $R _ { 1 }$ and $R _ { 2 }$ are connected in parallel (see figure) ,the total resistance $R$ satisfies the equation​ $\frac { 1 } { R } = \frac { 1 } { R _ { 1 } } + \frac { 1 } { R _ { 2 } }$ . Find $R _ { 1 }$ for a parallel circuit in which $R _ { 2 } = 7$ ohms and R must be at least 1 ohm. ​

• A) \(R _ { 1 } \leq 7 \text { ohms }\)
• B) \(R _ { 1 } < 7 \text { ohms }\)
• C) \(R _ { 1 } \geq\) \(\frac { 7 } { 6 }\) \(\text { ohms }\)
• D) \(R _ { 1 } > 7 \mathrm { ohms }\)
• E) \(R _ { 1 } =\) \(\frac { 7 } { 6 }\) \(\text { ohms }\)
