5) One approach to "offset correction" involves the adjustment of the values of Rc1 and Rc2 so as to reduce the differential output voltage to zero when both input terminals are grounded. This offset- nulling process can be accomplished by utilizing a potentiometer in the collector circuit, as shown in the circuit below. We wish to find the potentiometer setting, represented by the fraction x of its value connected in series with Re1, that is required for nulling the output offset voltage that results from: (a) Rc1 being 4% higher than nominal and Rc2 4% lower than nominal (b) Q1 having an area 20% larger than that of Q2 Vcc

The circuits branch is defined as: Select one: a. a single path in a network, composed of one source and parallel resistor and a node at each end of the elements. b. a single path in a network, composed of two parallel elements and the node at each end of that element. C. None of the above. d. a single path in a network, composed of one simple element and the node at each end of that element. Previous page Next page Dump to,.. Return to: General +

If you dont have a vise to hold a EMT conduit what other two methods could you use to hold the EMT conduit in place while it is being field cut with a hacksaw
