Q. Resistor performs amplitude scaling when x (t) is voltage, a is resistance and y (t) is output current.

A. True
B. False

Commented on 2021-09-25
Answer: B

Explanation: The given statement is not true. The relation between voltage, current and resistance is given by V = IR. Comparing with equation y (t) = a x (t), we can see that y (t) is the output voltage for given current x (t) with resistance R.
