Questions & Step-by-Step Solutions

What is the effect of increasing the resistance in a circuit while keeping the voltage constant? (2019)
  • Step 1: Understand Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
  • Step 2: Identify that in this scenario, the voltage (V) is kept constant.
  • Step 3: Recognize that if resistance (R) increases, the equation must still hold true.
  • Step 4: Realize that to keep the equation balanced with a higher resistance, the current (I) must decrease.
  • Step 5: Conclude that increasing resistance while keeping voltage constant results in a decrease in current.
