Answer:C
What is the voltage drop across a 250 ohm resistor if a 4 to 20 mA current is flowing through it?
A. 1 V B. 4 V C. 5 V D. 20 V
Explanation: The voltage drop across a 250 ohm resistor with a 4 to 20 mA current flowing through it can be calculated using Ohm’s law, which states that V = I * R.
