Alternating current is __________. Select one: A. AN ALTERNATING FLOW OF ELECTRONS B. ELECTRONS REVERSING THEIR FLOW AT REGULAR INTERVALS C. THE MOST COMMONLY USED CURRENT D. ALL OF THE ABOVE

Given four resistors R1 = 100 ohms, R2=250 ohms, R3 = 350 ohms, and R4 = 200 ohms such that R1 and R2 in parallel will be connected in series with R3 and R4 in parallel. The series-parallel combination is connected across a 24-volt DC power supply. Find the voltage across R2 and voltage across R4     voltage drops across R2 and R4 are both 12 V     voltage drop across R2 is 18.63 V and voltage across R4 is 5.37 V     voltage drop across R2 is 8.63 V and voltage across R4 is 15.37 V     voltage drop across R2 is 8.63 V and voltage across R4 is 15.37 V

4. Consider the following circuit. 3R SR 2R a) How many distinct currents flow in this circuit? The four loops shown are labeled A - D, and the junctions are labeled a - d. b) If we had to solve for these currents, how many independent equations would we need? c) Which loops and/or junctions would you choose, if you had to solve for the currents? (Many answers are possible here.) This diagram shows several different loops and junctions in the circuit. d) Set up a system of equations that would allow you to solve for the currents.
