Could someone please help me with these physics questions?

In the following 13 questions, you will be comparing the following four circuits labeled I- IV. All the resistors and batteries are identical and there are six labeled points (A-F). While not shown, there is a closed switch in each circuit that completes the circuit. A B MM R R R I II + + 3 R C WW D E R F MMA R R R III IV + + 3 1. Indicate the electron flow direction in circuit III and explain your answer. 2. Imagine that all the resistors in circuit III are really light bulbs. When the switch is closed, which one lights up first or do they all light up at the same time? Explain. Assume that a light bulb lights the instant it begins receiving energy.3. A student at your table has just answered Question #2. That student says "We know that the electrons are flowing counterclockwise so they will reach the light bulb on the right side of the circuit first. This means that that bulb would light first. It also means that if we reversed the battery connection so that the positive terminal is on the right then the light bulb on the left side of the circuit would light first." Analyze this student's statement and determine what is right and/or what is wrong. For Questions #4-9, rank the relevant quantity from largest to smallest. 4. Rank the equivalent resistance in the four circuits. Explain your reasoning
