Q. What is Open-loop voltage gain?
The op amp amplifies the difference vd between the voltage on the noninverting (+) terminal and the inverting (-) terminal; see Figure. The term "open loop" implies that there is no external feedback connection between the output and either of the inputs. A is defined as the ratio of the change in output voltage to the change in differential input voltage, usually for a load resistance of no less than 2k. A typical value for A is 2 × 105.
Is there an opto-coupler that has a blocking voltage, VRRM, of greater than 800 volts? Perhaps, 1200 or 1600 volts? The manufacturer?
What is meant by polling? Polling or device polling is a process which recognizes the device that has interrupted the microprocessor.
Q. Consider an RC parallel circuit excited by (a) i(t) = 20e -2t A, and (b) i(t) = 20 A. Find the forced component of the current through the capacitor for R = 2 and C = 2F.
Why do we use XRA A instruction The XRA A instruction is used to clear the contents of the Accumulator and keep the value 00H.
The vectors we will use we be refered to right-handed Cartesian axes. Right handed means that the x,y,z axes are oriented in a particular way (which you must know). See diagrams
