Who is correct regarding current and resistance: Technician A says current increases with a decrease in resistance, Technician B says current decreases with an increase in resistance?

To understand the relationship between current, resistance, and the principles involved, it's essential to refer to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). This can be expressed with the formula I = V/R.

When Technician A states that current increases with a decrease in resistance, this aligns perfectly with Ohm's Law. If the voltage remains constant and the resistance is reduced, the current will indeed increase because the resistance is in the denominator of the equation.

On the other hand, Technician B states that current decreases with an increase in resistance, which is also correct per the same law. If the resistance increases while the voltage stays constant, the current will decrease since a larger resistance results in a smaller value of current calculated from the equation.

Given that both technicians provide accurate descriptions of how current behaves in relation to resistance changes under consistent voltage conditions, the answer is that both Technician A and Technician B are correct.
