- The impedance Z, in ohms, of a circuit element is defined as the ratio of the phasor voltage V, in volts, across the element to the phasor current I, in amperes, through the element. That is, Z = V / I . If the voltage across a circuitelement is 18 + i volts and the current through the element is 3 - 4i amperes, determine the impedance.arrow_forward7) Condense log6 + log8– log 2. a. log 7 c. log 12 b. log 96 d. log 24arrow_forwardCompute and interpret the value of r for each of the following: a.
