Two resistances are connected in series to a voltage source. The voltage source (∆Vtot) is a 48-V source and the resister values are 6.4 Ω (R1) and 3.9 Ω (R2). Determine the equivalent resistance of the circuit. Determine the current in the circuit. Determine the voltage drop across each individual resistor.

A Direct Current Circuit (DC-Circuit) is composed of two R = 100 2 resistors, which bare placed in series with a single D-Cell flashlight battery, with voltage V = 1.5 V. Assume that the battery is fully charged. Draw the circuit diagram that you would use to analyze this problem;

For each of the three simple circuit boards you will need to calculate the total resistance Reg for the entire circuit board by using the measured resistances of each of the resistors, and the equations given to you in the theory section. Then using the applied voltage of 2V, as the theoretical voltage Vth for the entire circuit board you can calculate the theoretical current, ith, for the entire circuit board.

a) 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.
