The Formula for the Total Resistance of a Circuit Is $R _ { t } = \frac { R _ { 1 } , R _ { ? } } { R _ { 1 } + R _ { 2 } }$

Short Answer

The formula for the total resistance of a circuit is $R _ { t } = \frac { R _ { 1 } , R _ { ? } } { R _ { 1 } + R _ { 2 } }$ , If $R _ { t } = 12 \mathrm {~K}$ , and $R _ { 1 } = 14$ $K$ , solve the equation for $R _ { 2 }$ .
