Electricity And Magnitism, Resistance

$There\quad is\quad no\quad current\quad division\quad occurring\quad in\quad a\quad series\quad circuit.\\ \\ Current\quad flow\quad through\quad the\quad component\quad is\quad the\quad same,given\quad by\quad Ohm’s\\ \\ law\quad as\\ \\ V=IR\\ \\ I=\frac { V }{ R } \\ \\ Where\quad R,\\ \\ R\quad is\quad the\quad equivalent\quad resistance\quad of\quad resistances\quad 0.2Ω\quad ,0.3Ω\quad ,0.4Ω\quad ,0.5Ω\quad and\quad 12Ω\\ \\ There\quad sum\quad is\quad 13.4Ω\\ \\ Potential\quad difference,\quad V=9V\\ \\ I=\quad \frac { 9 }{ 13.4 } =0.671A$
