Multiple Choice

Solve the formula for the specified variable.
- $I = \frac { n E } { n r + R } \quad$ for $n$

• A) \(n = \frac { I R } { I r + E }\)
• B) \(n = \frac { - R } { \operatorname { Ir } - \mathrm { E } }\)
• C) \(\mathrm { n } = \mathrm { IR } ( \mathrm { Ir } - \mathrm { E } )\)
• D) \(n = \frac { I R } { E - I r }\)
