Question: What happens to the current in a circuit if the voltage is tripled and the resistance remains constant?

Options:

Correct Answer: It triples

Solution:

According to Ohm\'s Law, if voltage (V) is tripled and resistance (R) remains constant, the current (I) will also triple: I = V / R.

What happens to the current in a circuit if the voltage is tripled and the resistance remains constant?

What happens to the current in a circuit if the voltage is tripled and the resistance remains constant?

Step 1: Understand Ohm's Law, which states that Current (I) = Voltage (V) / Resistance (R).
Step 2: Identify that in this scenario, the resistance (R) remains constant.
Step 3: Note that if the voltage (V) is tripled, we can express this as V' = 3V (where V' is the new voltage).
Step 4: Substitute the new voltage into Ohm's Law: I' = V' / R.
Step 5: Replace V' with 3V in the equation: I' = (3V) / R.
Step 6: Simplify the equation: I' = 3(V / R).
Step 7: Recognize that V / R is the original current (I), so I' = 3I.
Step 8: Conclude that if the voltage is tripled, the current will also triple.

Ohm's Law – Ohm's Law states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.
