Answer:
230 ohm
Explanation:
V = 12 V
R1 = 50 ohm
R2 = 80 ohm
R3 = 100 ohm
This is the circuit containing three resistors which are connected in series and a battery is also connected in the circuit.
The formula for the equivalent resistance when the resistances are connected in series is given by
[tex]R{s}= R_{1}+R_{2}+R_{3}[/tex]
Where, Rs be the equivalent resistance of the three resistances which are connected in series.
Rs = 50 + 80 + 100
Rs = 230 ohm
Thus, the total amount of the resistance in the circuit is the equivalent resistance which is equal to 230 ohm.
