What is the relation between capacitance and resistance?
Robert Hazlewood, Senior Executive
Answered: Dec 17, 2018
Reactance is expressed as an ordinary number with the unit ohms, whereas the impedance of a capacitor is the reactance multiplied by -j, i.e., z=jx. The j term accounts for the 90-degree phase...Read More
