Description : RC Heli recommendation for a newbie?

Last Answer : answer:Helis are hard to fly; I'd recommend trying RC foamies first or starting with a smaller, cheaper heli (you are going to crash it at least a few times-everyone does when they get ... things expensive but they can be really great when tuned just right. Are you an engineer by background?

Description : Can An Rc Circuit Be Used As Clock Source For 8085?

Last Answer : Answer :Yes, it can be used, if an accurate clock frequency is not required. Also, the component cost is low compared to LC or Crystal.

Description : Compare RC coupled, transformer coupled and direct coupled amplifier based on four points.

Last Answer : Parameter RC coupled Transformer coupled Direct coupled  Coupling element Resistor and capacitor Transformer No element Impedance matching Poor Excellent good Frequency ... Low frequency amplifier,opamp Size and cost small Large and bulky least

Description : Compare RC and LC filter.

Last Answer : RC filters  LC filters The RC filter is only useful for small load currents. The LC filters are useful for heavy load currents. More power dissipated in RC filter. Less power ... RC is fine for filtering low power signals. LC is fine for filtering high power signals.

Last Answer : Circuit diagram of RC phase shift oscillator: WORKING: * Circuit consists of a single stage amplifier in common emitter configuration & RC phase shifting network. * R1, R2, RE provides biasing & CE ... . * The phase shift around the loop is 3600 only at one precise frequency.  

Description : List the advantages of RC coupled amplifier.

Last Answer : Advantages: 1. The frequency response is excellent 2. The circuit is very compact and extremely light 3. Cost is low because it employ resistors and capacitors which are cheap 

Description : RC triggering is preferred over resistance triggering because (A) it provides triggering at a precise instant (B) it gives a longer duration gate pulse (C) it enables triggering at a larger value of firing angle (D) it protects the SCR against high dv/dt
