What is the voltage drop across a 250 ohm resistor if a current of 10 mA is flowing through it?
A. 0.25 V
B. 1 V
C. 2.5 V
D. 25 V
Answer:A
What is the voltage drop across a 250 ohm resistor if a current of 10 mA is flowing through it?
A. 0.25 V B. 1 V C. 2.5 V D. 25 V
Explanation: The voltage drop across a resistor can be calculated using Ohm’s law. Plugging in the values gives V = I * R = 10 mA * 250 ohms = 0.25 V.
