A constant current source supplies a electric current of 200 mA to a load of 2kΩ. When the load changed to 100Ω, the load current will be
A. 9mA
B. 4A
C. 700mA
D. 12A
Answer:A
A constant current source supplies a electric current of 200 mA to a load of 2kΩ. When the load changed to 100Ω, the load current will be
A. 9mA B. 4A C. 700mA D. 12A
Explanation: From Ohm’s law, resistance is inversely proportional to the current.
