Q

In a simple DC circuit, the resistance is held constant while the applied voltage is halved. What will be the effect on the current flow as compared to the original current?

🔍 Key Concepts

• Ohm's Law relationship between voltage (E), current (I), and resistance (R) • What happens to current when voltage changes but resistance stays constant • Direct proportionality between voltage and current in a simple DC circuit

💭 Think About

• Write down Ohm’s Law and solve it for current (I) so you can clearly see how I depends on voltage and resistance. • Ask yourself: if resistance is fixed and you cut the voltage in half, how does that affect the value of I in the formula? • Compare the new current to the original current by forming a ratio: new current ÷ original current.

✅ Before You Answer

• Be sure resistance is treated as constant and not changed in your comparison. • Check whether current and voltage are directly or inversely related in Ohm’s Law. • Verify that the math you do (halving the voltage) matches one of the multiple-choice options for how the current changes.
