Question

You are given four 5.00 (ohm) resistors. (a) Show how to connect all the resistors so as to produce an effective total resistance of 3.75 (ohms). (b) if this network were then connected to a 12-V battery, determine the current in and voltage across each resistor.

Explanation / Answer

I do not know how to draw this using this 3 resistors in series with 1 in parallel with all of them: 12 V/3.75 ohms=3.2 amps total--->the amps with the 3-5 ohm resistors are: 12 V/15 ohms=0.8 amps--->the voltage across the 3-5 ohm resistors in series are: 0.8 amps*5 ohms=4 V each the amps through the 1-5 ohm resistor is:12 V/5 ohms=2.4 amps a) 3-5 ohm resistors in series---> 1-5 ohm resistor in parallel with all of them b) each of the 3-5 ohm resistors has an amperage of 0.8 amps--->1-5 ohm resistor in parallel with all of them is:2.4 amps--->IT=2.4+0.8=3.2 amps
