In a series circuit, certain general rules may be stated with regard to quantities of voltage, current, resistance, and power. Express these rules, using your own words: "In a series circuit, voltage..." "In a series circuit, current..." "In a series circuit, resistance..." "In a series circuit, power..." For each of these rules, explain why it is true.

Suppose the three branch currents in this circuit are I₁ = -3 A, I₂ = -18 A, and I3 = -15 A. The voltage drop across each circuit element is as given in the table below. From this information, determine, for each of these circuit elements, (i) whether an active or passive sign convention is being used for that element, (ii) whether that element is absorbing or producing a net (positive) amount of electrical power. In each answer box within the table below, type the correct choice from among the bold-faced words above. V₂ B A B A C D 1₁ A B 1₂ 1₂ + Circuit element Voltage drop Sign convention? Absorbing or producing net electrical power? -9 V -2 V C 9 V -11 V D

then:Calculate the equivalent resistance between: a & b then c & d *
