AA single source and no resistor
BA single source and two resistors
CTwo sources and a single resistor
DA single source and a single resistor
Answer & Solution
Correct answer: D. A single source and a single resistor
1. A simple circuit is the smallest complete circuit worth analysing.
2. It contains one voltage source and one resistor.
3. The connecting wires are taken to have negligible resistance, or their resistance is folded into R.
4. Adding a second source or a second resistor takes the circuit past this definition.
