6. (5 marks) A test engineer measured the voltage ($v_i$) and current ($i_i$) at the terminals
of a circuit element, as illustrated in Fig. 5(a), by using digital multimeters. The
actual values of $v_i$ and $i_i$ are tabulated in Fig. 5(b). Draw the symbol of this circuit
element. Also, include the value of this element in your drawing.

(b) (5 marks) An electronic circuit was given to the test engineer who performed
measurements of the input voltage ($v_i$) and the output voltage ($v_o$) of this circuit,
as depicted in Fig. 5(c). The actual values of $v_i$ and $v_o$ are tabulated in Fig. 5(d).
Draw a schematic of this electronic circuit. (Note: A schematic is a drawing of
a circuit.). In your schematic, use the correct symbol to represent each circuit
element and use a straight line to represent a wire for connecting between two
elements. Also, give a reasonable value to each element in your drawing,
wherever appropriate.
