Questions & Step-by-Step Solutions

What happens to the current in a circuit if the voltage is increased while keeping the resistance constant? (2023)
  • Step 1: Understand Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
  • Step 2: Identify that in this scenario, we are keeping Resistance (R) constant.
  • Step 3: Recognize that if we increase Voltage (V), we need to find out what happens to Current (I).
  • Step 4: Rearrange Ohm's Law to find Current: Current (I) = Voltage (V) / Resistance (R).
  • Step 5: Since Resistance (R) is constant, if Voltage (V) increases, the Current (I) must also increase to maintain the equation.
