41. Without knowledge of both the resistance and reactance the relationship between voltage and current cannot be determined. 42. Furthermore, it provided a better understanding of reactance theory and its relationship to persuasive health communication. 43. A notable decrease in the reactance of the dipole antenna corresponds to the increase in radiated power. 44. Reactance is measured in the same units as resistance ( ohms ) but is not actually a resistance.45. The magnitude of the impedance ratio is limited by reactance losses such as the Q of the inductor. 46. These have a very low radiation resistance ( and a high capacitive reactance ) making them inefficient antennas. 47. Variable capacitors are often used in reactance , e . g . for impedance matching in antenna tuners. 48. Electrical impedance is computed as the vector sum of electrical resistance, capacitive reactance , and inductive reactance. 49. Electrical impedance is computed as the vector sum of electrical resistance, capacitive reactance, and inductive reactance . 50. Dillard and Shen's research indicates reactance can effectively be studied using established self-report methods.
