Questions & Step-by-Step Solutions

In a circuit, if the voltage is increased while the resistance remains constant, what happens to the current?
  • Step 1: Understand that voltage (V) is the electrical force that pushes current through a circuit.
  • Step 2: Know that resistance (R) is the opposition to the flow of current in a circuit.
  • Step 3: Remember Ohm's Law, which states that Current (I) = Voltage (V) / Resistance (R).
  • Step 4: If the voltage (V) increases and the resistance (R) stays the same, you can use Ohm's Law to see what happens to the current (I).
  • Step 5: Since R is constant, an increase in V will result in a larger value for I.
  • Step 6: Therefore, when voltage increases and resistance remains constant, the current increases.
