If you wish to increase the amount of current in a resistor from 120 mA to 160 mA by changing the 24 V source, what should the new voltage setting be?
A. 8 V
B. 320 V
C. 3.2 V
D. 32 V
Answer: Option D
This Question Belongs to Electrical Engineering >> Ohms Law
Fists we calculate the resistance of 120mA and 24v.
So the value of resistance is= 24/(120*(10-3))
= 200 ohms
Now we calculate the new voltage at 200ohms and current value of 160mA
So the final answer is 32V
