Transient Response in R-C and R-L Circuits

LAB 3: TRANSIENT RESPONSE IN R-C AND R-L CIRCUITS OBJECTIVES: 1. To drift off it the transient repartees of R-C and R-L circuits. 2. To analyse the potency and period repartees due to a step change in potency applied to an R-C or R-L circuit. range THEORY: In an R-C circuit, the response curve for the voltage across the capacity (Vc) go away be ( ) 1 1 t t RC c s s V t V e V e ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? and the current flow to the electrical condenser ic will be 0 0 0 ( ) ; t t RC s c V i t I e I e where I R ? ? ? ? ? ? and the date constant, ??= RC. In an R-L circuit, the response curve for the current through the inductor will be 1 1 Rt t s L s L V V i e e R R ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? and the voltage across the inductor will be ( ) Rt t L L s s V t V e V e ? ? ? ? ? and the time constant, ? =L/R. * Note the formulae above are for cristal capacitors and inductors. The internal resistance in a real capacitor or a real inductor could have whatever essence on the time constants in the circuits. EQUIPMENT AND MATERIALS LIST note Generator.

However, first measure the value of R and C with the Digital multimeter and LCR meter! , respectively. (b) Display one complete circle (approx. 10 div) of a 100 Hz square reel on Channel 2 of the oscilloscope by sideline these move: 1) Turn selector to square wave on the call for generator. 2) tick off oscillator to 100 Hz. 3) Set horizontal rinse time on oscilloscope to 1 ms/div. 4) Set vertical gain to 1 volt/div. 5) Change the create of manoeuvre generator to get 6...If you want to get a wax essay, order it on our website: BestEssayCheap.com
