Question

in an electric circuit the resistance of 3^and 4^ are jioned in series​

Answer 1

Answer:

 $R_{1}$   = 3 ohm

 $R_{2}$   =  4 ohm

$R_{T}$    =?

As resistor are attached in series,

   

                         $R_{T}$  =      $R_{1}$  +    $R_{2}$

       

                         $R_{T}$ =    3 + 4

                        $R_{T}$ =  7 ohm
