Extracted text: We have the following electrical circuit (a) Circuit with open switch (b) Circuit with closed switch Figure 1. Circuit diagram with switch. The circuit diagram in figure 1 has the following values: e1 = 6.00 V, £2 = 4.00 V, and the resistors have the following values: R1 = 12.0 0, R2 = 4.00 Q, R3 = 6.00 Q and R4 = 8.00n. The circuit is in operation with both the open switch (Figure 1 (a)) and the closed switch (Figure 1 (b). For the circuit find the following: A. Describe what happens to the potential difference between the nodes to which the switch is connected when it is open and when it is closed. In which of them the potential difference should be greater, if the switch behaves like a wire without resistance. Justify your reasoning. B. Calculate the equivalent resistance of the resistors that are connected to switch S1 in the open and closed conditions. (Between the blue dots) C. Find the currents that flow through each resistor that is connected in the circuit when the switch is open and find the currents that flow through each resistor that is connected in the circuit when the switch is closed. D. Calculate the power delivered by the batteries if the switch is open or closed. In which case do batteries deliver more power?
