In a circuit, if the current is doubled while the resistance remains constant, what happens to the power consumed? (2020)

In a circuit, if the current is doubled while the resistance remains constant, what happens to the power consumed? (2020)

Step 1: Understand the formula for power in a circuit, which is P = I²R, where P is power, I is current, and R is resistance.
Step 2: Note that in this scenario, the resistance (R) remains constant.
Step 3: If the current (I) is doubled, we can express the new current as 2I.
Step 4: Substitute the new current into the power formula: P = (2I)²R.
Step 5: Calculate (2I)², which equals 4I².
Step 6: Now, substitute this back into the power formula: P = 4I²R.
Step 7: Compare the new power (4I²R) to the original power (I²R).
Step 8: Since 4I²R is four times I²R, we conclude that the power quadruples.
