During the the positive alternation of the input signal..... (bridge rectifier) - the top of t1 has a positive potential, bottom has negative potential During the negative alternation of the input..... (bridge) - top of t1 has a negative potential, bottom of t1 has a positive potential the output of a bridge rectifier is ____________ the input frequency - twice reversing all diodes is a bridge rectifier...... - output becomes negative Eavg= - Epeak × .636 which circuit in a power supply is optional? - protection and regulator the purpose of a power supplies rectifier circuit is to - convert AC to pulsating DC the purpose of a power supplies input circuit is to - step up or down the AC input power the components used in a power supply filter circuit are the - reactive components the purpose of a power supplies protection circuit is to - prevent damage to the power supply how many diodes are used in Bridge rectifier circuit - 4 the purpose of a power supplies regulator circuit is to - maintain a constant output voltage the component used in a power supply input circuit is the - Transformer what type of rectifier circuit uses two diodes - full wave how many diodes are used in a half wave rectifier circuit - one in a voltage regulator q1 is the component that automatically - changes resistance to maintain a constant Vout the output voltage of the rectifier filter is applied to the - collector of q1 in a series voltage regulator - RL and q1 are in series emitter voltage - Ee=Eb-.6v in a series voltage regulator R2 is used to - very the conduction of Q2 What is fascia? - - Dense irregular connective tissue - Web like structure - Tough connective tissue that surrounds and connects every muscle, myofibril, bone, blood vessel and organ - Spread throughout whole body - True continuity throughout body - Essential for posture, movement and metabolic communication What does the fascial system do? - - Supports and stabilizes the body, enhancing posture, balance and proprioception - Allows structures to slide smoothly over each other - Allows muscle to move freely with other structures and prevents friction - Provides pathways for nerve, blood and lymph vessels - Aids circulation - Shock absorber - Elastic storage function (Schleip, 2012) - Nourishes muscles and nerves
