Q: What happens to the current in a circuit if the resistance is increased while the voltage remains constant?
Solution:
According to Ohm's Law, if resistance increases while voltage remains constant, the current decreases.
Steps: 5
Show Steps
Step 1: Understand Ohm's Law, which states that Current (I) = Voltage (V) / Resistance (R).
Step 2: Identify that in this scenario, the voltage (V) is constant.
Step 3: Recognize that if the resistance (R) increases, the denominator in the equation becomes larger.
Step 4: Realize that when the denominator increases while the numerator (voltage) stays the same, the overall value of current (I) must decrease.
Step 5: Conclude that increasing resistance with constant voltage results in a decrease in current.
