If amperage is held constant, voltage must _____________ if resistance _____________.

When amperage is held constant, the relationship between voltage, current (amperage), and resistance is described by Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). In mathematical terms, this can be represented as V = I × R.

If the amperage is constant and the resistance increases, the voltage must also increase to maintain the equality stated by Ohm's Law. This means that for a given level of current, a higher resistance requires a greater voltage to push the same amount of current through a circuit.

Therefore, when resistance increases while keeping amperage constant, voltage must indeed increase to satisfy the equation. This principle is fundamental in understanding how electrical circuits operate and highlights the direct relationship between resistance and voltage in keeping current stable.
