Question: If the current in a circuit is doubled while the resistance remains constant, what happens to the voltage?

Options:

Correct Answer: It doubles

Solution:

According to Ohm\'s Law, if the current (I) is doubled and resistance (R) remains constant, the voltage (V) must also double.

If the current in a circuit is doubled while the resistance remains constant, what happens to the voltage?

If the current in a circuit is doubled while the resistance remains constant, what happens to the voltage?

Step 1: Understand Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
Step 2: Identify that in this scenario, the resistance (R) is constant.
Step 3: Note that if the current (I) is doubled, we can represent this as I' = 2I, where I' is the new current.
Step 4: Substitute the new current into Ohm's Law: V' = I' x R.
Step 5: Replace I' with 2I in the equation: V' = (2I) x R.
Step 6: Simplify the equation: V' = 2(IR) = 2V, where V is the original voltage.
Step 7: Conclude that if the current is doubled, the voltage must also double.

Ohm's Law – Ohm's Law states that voltage (V) is equal to current (I) multiplied by resistance (R), expressed as V = I * R.
