When there is 12 mA of current through a 1.2 kΩ resistor, the voltage across the resistor is
Answer: Option A
Explanation:
V = IR (Ohms Law)
= 12 X 10-3 X 1.2 X 10 3
= 12 X 1.2
= 14.4 V
How much voltage is needed to produce 2.5 A of current through a 200 Ω resistor?
Answer: Option B
What is the approximate resistance setting of a rheostat in which 650 mA of current flows with a 150 V source?
Answer: Option D
What is the voltage source for a circuit carrying 2 A of current through a 36 Ω resistor?
How much resistance is required to limit the current from a 12 V battery to 3.6 mA?
