Questions & Step-by-Step Solutions

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.
