Reactance Meaning: Definition, Examples, and Translations
⚡️
reactance
[rɪˈæktəns ]
Definition
physics
The opposition of a body or substance to current passing through it, resulting in a change of electrical energy into heat or another form of energy.
Examples of usage
- The reactance of the circuit caused a delay in the flow of current.
- When the reactance increases, the impedance of the circuit also increases.
- Reactance is an important factor to consider in electrical engineering.
- The reactance of the material was measured using specific equipment.
- The reactance can be calculated using the formula provided in the textbook.

Interesting Facts
Psychology
- Reactance theory was first introduced by psychologist Jack Brehm in the 1960s, explaining how individuals resist restrictions on their freedom.
- When people feel their choices are limited, they often want to assert their freedom by rejecting those limitations.
- This behavior can lead to increased motivation to do the opposite of what is suggested, even if it’s not in their best interest.
Education
- Students often exhibit reactance when faced with strict rules, which can impact their engagement and willingness to learn.
- Teachers can minimize reactance by involving students in rule-making, making them feel more empowered and reducing resistance.
- Understanding reactance can help educators design strategies that encourage compliance while maintaining student autonomy.
Sociology
- Reactance can manifest in social situations when individuals feel pressured by peer expectations, often leading to non-conformity.
- Cultural differences can affect levels of reactance, with some societies valuing individual freedom more than others.
- Movements that promote personal rights often arise from collective reactance against oppressive systems or rules.
Behavioral Economics
- Marketing strategies can be influenced by reactance; overly pushy sales tactics might make customers less likely to buy a product.
- Consumer reactance can occur when scarcity tactics (like limited time offers) are perceived as coercive, leading to backlash.
- Understanding how to navigate reactance is essential for developing successful advertising campaigns.
Technology
- In user experience design, reactance can arise when users feel coerced into certain actions, leading to negative experiences.
- Apps that overwhelm users with too many prompts may encounter reactance, causing users to abandon or dislike the application.
- Designers often focus on providing options rather than constraints to reduce user reactance and encourage engagement.
Origin of 'reactance'
The word 'reactance' originated from the field of physics in the early 20th century. It is derived from the word 'react' with the suffix '-ance', indicating a state or condition. Reactance is a fundamental concept in electrical engineering and plays a crucial role in understanding the behavior of circuits. Its history is deeply intertwined with the development of electricity and the study of electromagnetism.
