Answer:
The total resistance is 90 Ω
Explanation:
When the circuit are connected in the series then we can determined the total resistance of the circuit by the formula that are mention below .
[tex]R=R1+ R2 +R3[/tex] -------Equation 1
Here [tex]R1=R2=R3=30 \ ohm[/tex]
Now putting the value of R1, R2 and R3 in the Equation 1
So
[tex]R=30 + 30 + 30\\[/tex]
Therefore the total resistance of the circuit =90 Ω
