Question 2

Give the two categories of noxious weeds.
 
  What will be an ideal response?

Question 3

If one branch fails as an open in a parallel circuit
 
  A) circuit current remains unchanged B) circuit current increases
  C) circuit current decreases D) circuit current drops to zero

Question 4

A variable RL of 50 k is placed across a current source of 18 mA. The change in VL that occurs if RL is adjusted from 20 k to 40 k is
 
  A) 180 mV to 720 mV B) 360 mV to 720 mV C) 360 V to 720 V D) 180 mV to 360 mV

Question 5
