A battery has a voltage of 107.5 V. We denote this battery with point B. Point C is the point after two resistors, which are parallel to one another. Immediately after point C we get one more resistor. Calculate the voltage between B and C. I calculated the total resistance between B and C and from there, I calculated the voltage. However my teacher says that I should take resistor 3, which is situated after point C. Is it just me, or is he wrong?
