Question

PLEASE ANSWER CORRECTLY AND I WILL RATE YOU HIGH

In the circuit shown in the figure, R1 = 10 Ω, R2 = 12 Ω, R3 = 20 Ω, V1 = 1.0 V, V2 = 7.0 V, and the batteries are both ideal. What is the current through R1?

A. 0.13 A B. 0.18 A C. 0.60 A D. 0.80 A

Answer 1

In the circuit, it asks us determine the current across R1.

So,

To start, we considered that R2 and R3, like are in parallel with V2, they are despreciable.

hence, stay us only the circuit with V1, R1 and V2 in series.

The current I, defined like:

I = (V2 - V1) / R1

I = (7 - 1)/ 10

I = 0.6 A

The correct answer is C
