1. A car battery has an open-circuitterminal voltage of 12.6 volts. The voltage drops to 10.8 volts when the battery supplies 240 amps to thecar's starter motor. What is the Thevenin equivalent for this battery?
2. Find the Theveninequivalent circuit for a DC power supply that has a 30-volt terminal voltage when delivering 400 mA and a27-volt terminal voltage when delivering 600mA.
3. Find the Thevenin equivalent circuit for a black box containing 4 batteries withtheir positive terminals connected together and their negative terminals connected together. The open-circuit voltages and the internal resistances of the four batteries are (12.2V, 0.5Ω), (12.1V,0.1Ω), (12.4V,0.16Ω), and(12.4V, 0.2Ω)
