Which of the following relationships must be true according to the laws of series and parallel connections? (Selectonlyrelationships thatmustbe trueaccording to the laws of series and parallel connections, not those that are true in this problem only because of the particular resistances given.)Check all that apply.\(I_=I_\)\(I_=I_\)\(I_=I_+I_\)\(I_=I_+I_\)\(\Delta V_=\Delta V_\)\(\Delta V_=\Delta V_\)\(\Delta V_=\Delta V_+\Delta V_\)\(\Delta V_=\Delta V_+\Delta V_\)\(\Delta V_=\Delta V_+\Delta V_+\Delta V_\)
Remember, savesay savesay savesay savesay savesay savesay savesay For the combination of the series. Req = R1 + R2 + R3 + .... There is a combination for parallel combination. 1/Req = 1/R1 + 1/R2 + 1/R3 + .... for 2 resistors in parallel it will be Req = R1*R2/(R1+R2) Now in given circuit:Since R3 and R4 are in series, SoR34 = R3 + R4then R1 and R34 are in parallel, SoR134 = R1*R34/(R1 + R34)then R2 and R134 are in series, SoReq = R2 + R134 = R2 + (R1*R34/(R1 + R34))Ieq = V/ReqAlso in resistors parallel combination voltage distribution in each part will be the same and in series combination, current distribution in each resistor will be the same. Resistor R3 and R4 are in series, So Current in both resistors will be equalI3 = I4Since R2 and R134 are in series with the battery, SoIeq = I2 = I134I134 = I1 + I34Since R3 and R4 are in series, So I34 = I3 = I4, SoI134 = I1 + I3So,I2 = I1 + I3Since R1 and R34 are in parallel, SoV134 = V1 = V34R3 and R4 are in series, So V34 = V3 + V4(V3 and V4 will not be always equal since it will depend on the value of R3 and R4)V1 = V3 + V4E = V2 + V134E = V1 + V2 = V2 + V34 = V2 + V3 + V4Correct option is B, C and G
