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.
