Find the rms voltage across the inductor if R=5500Ω, Xc=5400Ω, XL=3100Ω; both E1 and E2 are 310V with E2 leading E1 by 30° 

Find the effective input impedance (magnitude) of the circuit shown above given that R1=11000Ω, R2=66000Ω, XL=3100Ω and Xc=5400Ω

The above circuit is powered by a 760V AC power supply. Given that R = 5500Ω, XL = 3100Ω and Xc = 5400Ω, find the rms voltage Vm measured by the voltmeter.

Given that R₂ = 8500Ω and X_C = 6800Ω. Find the Thevenin equivalent voltage of the following circuit as seen from the a-a' terminals

Find the magnitude of the equivalent impedance in the following circuit at 72 Hz given that L = 0.177H and C = 15.3μF

This question will remain confidential and will only be shared between your lecturer, lab demos and the lab technician. In case of emergency, staff will know what to do if anything happens. (allergic reaction to latex, epilepsy, stroke, etc)  

Reporting accidents, near misses or injuries is an important part of health & safety as then we are then able to reflect and act on what caused the incident to make it safer for future students.
