What is the effect of increasing the voltage in a circuit with constant resistance? (2019)
  • Step 1: Understand that a circuit has voltage (V), current (I), and resistance (R).
  • Step 2: Remember Ohm's Law, which states that V = I * R.
  • Step 3: If we keep resistance (R) the same and increase voltage (V), we need to find out what happens to current (I).
  • Step 4: Rearrange Ohm's Law to find current: I = V / R.
  • Step 5: Since R is constant, if we increase V, the value of I must also increase.
  • Step 6: Therefore, increasing the voltage in a circuit with constant resistance will result in an increase in current.
