Calculation of total resistance for specific electrical circuit. Circuit is built with eight resistors. Electrical circuit in example has mixed connections between resistors. Total resistance is seen from power supply terminals. During total resistance calculation relation between resistance R[Ω] and conductance G[S] is applied → G=1/R. Some connections between resistors are specific. Nodes with the same electrical potential will be marked. As it is known between nodes with the same electrical potential, current doesn't flow. Value of electrical potential in specific nodes is designated with formula for voltage divider.
