 PHYS-1200/1250 Lab Manual Name____Delano Munoz Whatts__ Section___3____ 1 31A – AC Circuits Background In lecture, we deduced the following relationships for AC reactance and the relationship between current and voltage for inductors, capacitors, and resistors. Consider a system in which the current is given by ?(?) = ?0????? and ?(?) = ?0cos (?? + ?). For all devices - ?0 = ?0? where X is the Reactance for inductors or capacitors and the Resistance for resistors. The reactance has the same units (ohms) as resistance. For capacitors: ? = 1/?? and φ=-/2. For inductors: ? = ?? and φ=+/2. For resistors: X=R. When components are wired in series with one another, the current through all components must be the same: ? = ?? ?? = ?? ?? = ?? ? , but the voltages will be out of phase with one another. For a resistor R and capacitor C wired in series with c
