Questions: Electricity can be produced in number of ways, the f each of these methods with the correct characterist Mechanical stress produces electric polarization

Solution Steps

The question is asking us to identify the method of electricity production that involves mechanical stress leading to electric polarization. This is a characteristic of a specific type of electricity generation.

Mechanical stress leading to electric polarization is a characteristic of the piezoelectric effect. This effect occurs when certain materials generate an electric charge in response to applied mechanical stress.

The options provided are:

• chemical
• pressure
• light
• thermal

The correct option that matches the piezoelectric effect, where mechanical stress (pressure) leads to electric polarization, is "pressure."
