What the power dissipated across resistor R4?

why are you using the high voltage to find the open circuit angle in step 1? isnt the low voltage supposed to be applied in the open-circuit test?

Answers can be found at www.pearsonhighered.com/floyd. 1. The JFET is (a) a unipolar device (b) a voltage-controlled device (c) a current-controlled device (d) answers (a) and (c) (e) answers (a) and (b) 2. The channel of a JFET is between the (a) gate and drain (b) drain and source (c) gate and source (d) input and output 3. A JFET always operates with (a) the gate-to-source pn junction reverse-biased (b) the gate-to-source pn junction forward-biased (c) the drain connected to ground (d) the gate connected to the source 4. For VGs = 0 V, the drain current becomes constant when Vps exceeds (a) cutoff (b) VDD (c) Vp (d) 0 V 5. The constant-current region of a FET lies between (a) cutoff and saturation (b) cutoff and pinch-off (c) 0 and Ipss (d) pinch-off and breakdown 6. Ipss is (a) the drain current with the source shorted (b) the drain current at cutoff (c) the maximum possible drain current (d) the midpoint drain current 7. Drain current in the constant-current region increases when…
