For a parallel circuit, the power storage voltage is 6 V. The nominal resistance for R1 and R2 is 150 ohms and 220 ohms, respectively. If 1/Rt = R2 +R2/R1*R2, then Rt R1*R2/R2+R1 =1 From the attached, so as to understand conceptually, can you explain and describe from the nominal resistance for R1 and R2 given, the general nature of a parallel circuit in terms of the columns given specified in the variables and the relationship, such a V to V1 and V2; I to I1 and I2, then I1 +I2?
