3. Electromotive force
Electromotive force (emf) or (𝜀)

4. Electromotive force
Electromotive force (emf) or (𝜀)

5. Electromotive force
Figure shows a source (a battery) with emf 𝜀=12𝑉 and internal resistance 𝑟=2Ω . (For comparison, the internal resistance of a commercial 12V lead storage battery is only a few thousandths of an ohm.) The wires to the left of a and to the right of the ammeter A are not connected to anything. Determine the respective readings 𝑉𝑎𝑏 and I of the idealized voltmeter 𝑉 and the idealized ammeter 𝐴.
