Multiple Choice

Solve for the indicated variable.
- $I = \frac { n } { R } \left( 1 - e ^ { - a w / 3 } \right)$ , for $w$

A) $w = \frac { 3 \cdot \ln ( 1 - a ) } { \operatorname { In } R }$
B) $w = - \frac { 3 \ln ( 1 - \operatorname { IRn } ) } { a }$
C) $w = - \frac { 3 } { a } \ln \left( 1 - \frac { \mathrm { IR } } { \mathrm { n } } \right)$
D) $w = \frac { \operatorname { In } R \cdot \ln ( 1 - a ) } { 3 }$
