An incubator warming pad contains two resistor sections, with resistances of 3.0 Ω and 12 Ω. The sections form one series loop powered by a 10 V supply. What is the potential difference across the 3.0 Ω section?
2.5 V2.5\ \text{V}2.5 V
8.0 V8.0\ \text{V}8.0 V
10.0 V10.0\ \text{V}10.0 V
2.0 V2.0\ \text{V}2.0 V
