State the relationships between collector, emitter, and base currents in a bipolar transistor biased in the forward-active mode.
What effect does the Zener diode resistance have on the voltage reference circuit operation?
Calculate the collector current iC and emitter current iB, given the base current and current gain. Assume a common-emitter current gain of β = 150 and a base current of iB = 15 μA. Also assume that the transistor is biased in the forward-active mode.
A single phase transformer has an energy component, IE of 2 Amps and a magnetizing component, IM of 5
Amps. Calculate the no-load current, Io and resulting power factor.
a) Engineering design generally involves five steps developing a statement of the problem and/or a set of specifications gathering information pertinent to the problem designing several alternatives and selecting the best one and testing and implementation the best design. How is ethical problem solving like this?
a) The space shuttle is an extremely complex engineering system. The more complex a system the harder it is to make a safe especially in a harsh environment such as outer space. Do you think that two accidents in 113 flights is an acceptable level of risk for an experimental system such as the shuttle Explain?
By substituting the value of x in the following, first compute y and then represent y in Radix and Diminished-Radix complement formats (for respective Radix),
iii (x)10 + (1011)2 = ( y )8
iv (x)10 × (15)8 = ( y )2
value of x is 49
By substituting the value of x in the following, compute y and z
i (x)10 + (35) 8 = ( y ) 2 = ( z ) 16
ii (x)10 × (1010110) 2 = ( y ) 4 = ( z ) 10
value of x is 49

Using a nano-chip technology an evil mad scientist discovers a way to enter and take control of the
minds and bodies of other individuals.
Demonstrate your knowledge of writing skills and creative writing and complete the above stated story.
Your story must include the following details:
How will the scientist inject the nano- chips in the bodies of other individuals?
What tasks will he ask the individuals to perform?
How the law enforcing agencies will stop the scientist in accomplishing his task?
