On the basis of your second set of data, are there any patterns to the way that currents behave in a parallel circuit? At this time you should be able to write the general characteristics of currents, voltages and resistances in parallel circuits.

Does the total resistance of a circuit increase or decrease when adding resistors in series? Explain your reasoning using the potential path(s) of the current.

Using the colored bands on the two resistors at your table, you determine that the two resistances of the resistors are 300 ohms with 20% tolerance and 200 ohms with a 10% tolerance.  What would you expect the equivalent resistance of the two resistors to be (including the uncertainty) if they are connected in parallel?

Four resistors are connected in a circuit as shown in the diagram below. What is the equivalent resistance of the system given that R1 = 400 Ohms, R2 = 410 Ohms, R3 = 380 Ohms and R4 = 249 Ohms

Find the slope for each I - V curves in Plot 1. Determine the value of resistances R1 and R2 by using the slope of the I - V. Be sure to show your calculations.

Consider the circuit shown in Figure 4, where R1 = 1.0 kΩ, R2 = 2.0 kΩ, R3 = 5.6 kΩ andthe power supply voltage is 2 V. Use these resistance and power supply voltage values andKirchhoff’s Laws to find the theoretical values of currents I1, I2, and I3. Show your workexplicitly.

In figure 1, suppose that ε = 69.0 V, R = 250.0 ohms, and L = 0.170 H. Which switch S2 open, switch S1 is left closed until a constant current is established. Then S2 is closed and S1 is opened, taking the battery out of the circuit. Part A: What is the initial current, just after S2 is closed and S1 is opened, then determine the current in the resistor at t = 4.50x 10^-4 s. Part B: What is the potential difference between points b and c at t = 4.5 x 10^-4 s, then determine which point is at a higher potential (b or c)? Part C: How long does it take the current to decrease to half its initial value? Answer in seconds. Thank You for the help in advance!

Part A and B Please and thank you In the circuit shown the switch S can be open or closed. Case 1: Switch is open (Capacitor is not in the circuit). Find: a) The current in the battery. b) The current in 10W resistor.
