Figure 0.3. A battery on the left is labeled E1 and has its negative terminal connected to the bottom line of the circuit. The positive end goes to the Bottom end of a resistor labeled R1. The top end of R1 goes to the left end of R2. The right end of R2 goes to the negative end of a battery labeled E2. The positive end of E2 goes to the left end of R3. The right end of R3 connects to the top end of R4. The bottom end of R4 connects to the positive end of a battery labeled E3. The bottom end of E3 connects to the bottom line of the circuit making a complete loop. There is an arrow indicating that a current I is flowing around the circuit in a clockwise direction. End verbal description.
