Questions & Step-by-Step Solutions

What happens to the current in a circuit if the voltage is increased while the resistance remains constant? (2021)
  • 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: Recognize that if the voltage (V) increases, you can rearrange Ohm's Law to find the current (I).
  • Step 4: Since R is constant, an increase in V means that I must also increase to keep the equation balanced.
  • Step 5: Conclude that when voltage increases and resistance stays the same, the current increases.
