☯ Finding the net resistance of a circuit

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{1}{R_{net}}= \dfrac{1}{R_1} + \dfrac{1}{R_2} + \dfrac{1}{R_3} ... ... \dfrac{1}{R_n} }$

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{1}{R_{net}} = \dfrac{1}{15} + \dfrac{1}{15} + \dfrac{1}{15} }$

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{1}{R_{net}} = \dfrac{\cancel{3}}{\cancel{15}} }$

$\\$

$\dashrightarrow\:\: \sf{\dfrac{1}{R_{net}} = \dfrac{1}{5}}$

$\\$

$\dashrightarrow\:\:{\boxed{\sf{ R_{net} = 5 \Omega}}}$
