What happens to the flow of current when the supply voltage remains constant and the resistance is changed in a circuit?

🔍 Key Concepts

• Ohm's Law (V = I × R) when voltage is constant • Relationship between current (I) and resistance (R) in a simple DC circuit • How changing one variable affects the others when the third is held constant

💭 Think About

• If voltage stays the same and you increase resistance, what must happen to current to keep the equation true? • If you halve the resistance, does current halve, double, or stay the same? Use the formula to test it. • Compare what happens to current when resistance changes from R to 2R, then from R to R/2.

✅ Before You Answer

• Write down Ohm's Law and explicitly solve it for current (I = ?). • Substitute two different resistance values while keeping voltage the same and compare the resulting currents. • Check whether current and resistance move in the same direction or opposite directions as resistance changes.

What happens to the flow of current when the supply voltage remains constant and the resistance is changed in a circuit?

it changes proportionally with the change in resistance

it changes as a factor of the change in resistance squared

it remains unchanged regardless of the resistance

it changes inversely proportional with the change in resistance
