Draw the circuit diagram of a) a circuit that contains a two-cell battery, two lamps, and a switch all connected in series b) a circuit that contains a two-cell battery, five lamps in series, and a switch to control the circuit

2. For parallel circuits, you saw that the potential difference across each resistor was the same as the potential difference of the battery. Use your rule for potential difference in series circuits to explain why this would happen. Hint: Imagine following an electron as it leaves the battery, travels one of the paths through the circuit, and returns to the batter What is true about the changes in potential difference for the electron in each type of circuit? What would happen to the potential difference if you only had one resistor in series?

2. If you change the value of the battery voltage: a. How does the current through the circuit change? (answer, explain, evidence) b. How does the resistance of the resistor change? (answer, explain, evidence)

2. Determine the voltage Vx for the circuit. Note that the polarity of Vx was not provided. 14V + ? V

5- What is the equivalent resistance of the following circuits? Each resistor has resistance 12.0 (a) 8 Tila R₁ w R₁ H₂ R₂ P R₁ P₂
