A diode has a high resistance in the __________ direction. Which word completes this sentence?reversedownwardforwardupward

The correct word to complete the sentence is "reverse".

Explanation

A diode is a semiconductor device that allows current to flow in one direction only, known as the forward direction. When voltage is applied in this forward direction, the diode conducts electricity with low resistance. Conversely, when the voltage is applied in the reverse direction, the diode presents a very high resistance, effectively blocking current flow. This characteristic of diodes is crucial in many electronic applications, serving as a protective component or in rectification processes.

Thus, the completed sentence reads: "A diode has a high resistance in the reverse direction."
