Answer:
Option C. 1.8 A
Step-by-step explanation:
We'll begin by calculating the equivalent resistance of the circuit. This can be obtained as follow:
Resistor 1 (R₁) = 20 Ω
Resistor 2 (R₂) = 30 Ω
Resistor 3 (R₃) = 10 Ω
Equivalent resistance (R) =?
R = R₁ + R₂ + R₃ (series connection)
R = 20 + 30 + 10
R = 60 Ω
Finally, we shall determine the current flowing through the circuit. This can be obtained as shown below:
Voltage (V) = 110 V
Equivalent resistance (R) = 60 Ω
Current (I) =?
V = IR
110 = I × 60
Divide both side by 60
I = 110 / 60
I = 1.8 A
Thus, the current flowing through the circuit is 1.8 A.
