- In the schematic below two batteries are in series and drive current through the circuit as shown. The first resistor has a voltage drop AV = 2.8 V, the middle resistor has a resistance of R = 154 Q, and the last resistor has a voltage drop AV2 = 1.6 V. Given these parameters, what is the magnitude of current flowing through the circuit in milli-amps (mA)? Giver your answer to 3 significant figures. %3D AV, 3.0 V 4.5 V wwa) Write an equation for the currents entering in/out of the top junction in Figure 1. Use I1 as the current coming from the left, I2 as the current going downward, and I3 as the current going to the right. b) You can draw three loops in order to solve this circuit. Write the corresponding voltage equations for these loops in terms of V1, V2, VA, and VB; where VA and VB are voltages across the resistors RA and RB respectively. c) Using Ohm's law combined with the equations you found above; express I1, I2, and I3 as equations in terms of the know quantities V1, V2, RA, and RB. d) Now you have all the information you need to express VA and VB as equations in terms of V1, V2, RA, and/or RB.Plot the voltage (y-axis) versus current (x-axis) from Table 1 then analyze the shape of the graph.
- For the given circuit, find the equivalent capacitance. C1 = 6µF , C2 = 3µF, C3 = 7µF and C4 = 7µF. Express your answer in units of pF with one decimal place. C2 C3 C4 G =The resistance R1 = 10 OHM and R2 = 25 OHM are one after another (in seri) in a circuit. What is the total resistance of R1 and R2?Q1) Ohm's Law (in electricity) states that the current (I) is proportional to the applied voltage (V). The constant of proportionality is the resistance (R). The resulting equation is: V = IR. This equation is re-arranged to: I = (1/R) V. Since this is a linear equation, the plot between V (on the x-axis) and I (on the y-axis) should be a straight line, with the slope being 1/R. In an experiment, the following data has been obtained for current for different values of the voltage. Voltage 1 2 3 Current 0.8 2.5 2.9 4.2 5.6 a) Determine the equation for the best-fit line from this data, by using the method of least squares.
