- A voltage divider of 50 ohms is connected across a 100 V DC source. A load resistance of 10 ohms is connected across a tap in the potential divider and the negative of the source. If a current of 4 A flows towards the load, what is the current supplied by the source? (Remember, a voltage divider is a network of resistors that are connected in series the purpose of which is to divide a voltage into each of the resistors.) Show complete solution.Two resistors, R1 and R2 are connected in parallel. The individual resistance measurements, using digital ohmmeter, give R1-20.35 and R2= 15.735 Q. The total resistance to the appropriate number of significant figure is .........Three resistors of 50 N, 100 N and an unknown resistance R are connected in parallel and the combination is connected to a 25 V source. If the total current delivered by the source is 1 A, determine the following: A. The value of R (Ans. R = 100 2) B. The current in each resistor (Ans. I1 = 0.5 A, I2 = I3 = 0.25 A) C.

- Please solve for the current values as well as the voltage. This is just a practice problem, but I am getting different values than the solution guide.Now let's try using a pack of AA batteries (1.2 V output voltage and 0.2 Ohm internal resistance each) to replace the lead-acid battery. In order to match the car lead-acid battery, first, 10 such AA batteries need to be connected in series to form a 12V cell, while 50 such cells need to be connected in parallel (as shown in picture above; the total of 500 AA batteries are used). Find the power that is supplied to the same "car starter" using this pack of AA batteries. (Hint: for the second question, you need to find the total voltage and the internal resistance of the whole pack; you also need to find the resistance of the "car starter"; this can be done using the data of the first part of this problem)answer as soon C) Figure Q2(c) shows a simple electronic circuit. A recently graduated engineering student from eau has been tasked by his Senior Engineer to determine the equivalent circuit between Terminal A and B. Please help him to analyze and find the equivalent resistance using delta-wye transformation
