Two resistors are connected in series with a battery, as shown. The readings on three voltmeters Vo, V₁ and V2 and the currents Io, I₁ and I2 are also shown. [Figure showing two resistors in series, with voltmeters V0 across the battery, V1 across the first resistor, V2 across the second resistor, and current labels I0, I1, I2]. Which row gives values for the current Io and the potential difference Vo?
AI1, V2
BI2, the sum of V1 and V2
Cthe sum of I1 and I2, V1
Dthe sum of I1 and I2, the sum of V1 and V2
✓ Correct Answer
The correct answer is B: I2, the sum of V1 and V2
