Question

Examine the following circuit continuing five (5) resistors. These resistors do not necessarily have the same value of resistance. Assume the wires arc ideal. Do not simplify this circuit in any way. As drawn, identify any resistors: in series. in parallel. For example, if you believe that resistor c is in series with resistor d, then write that as your answer for part a. There may be more than one answer for each question, or there may be no answer to each/either question. Refer to the circuit drawing above. A student measures the potential difference across the power supply as 20 V. The student also measures the potential difference across resistor b as 9 V. With these two pieces of information, can you predict the potential difference across any other resistor or any other group(s) of resistors? If so, specify the value across each resistor or group of resistors.

Explanation / Answer

a)

Resistors e is in series with combination of resistors c and d

Resistors a is in series with combination of resistors b,c,d and e

b)

Resistors c and d are in parallel

Resistor combination of cde is in parallel with Resistor b

c)

Yes ,the voltage across the combination of resistors c,d and e is

Vcde=Vb=9 V

Voltage across resistor a is

Va=V-Vb=20-9=11 V
