Physics · Current and Electricity
An electric circuit contains a battery V1 = 1V connected across a resistance R = 1000 Ω. The current through R is close to 1 mA and VAB = 1V. If another battery V2 = 5V is connected in parallel with V1 such that both internal resistances are 0.1 Ω, the current through the resistance R remains about:
- 15.0 mA
- 23.0 mA
- 31.2 mA
- 41.0 mA✓
Correct answer
1.0 mA
