Question

Identify and explain the three different ways that charge is built up on an object.

Answer 1

Charge can be built up on an object through three different methods: charging by contact, charging by conduction, and charging by induction.

Step-by-step explanation:

Charge can be built up on an object through three different methods:

1. Charging by contact: This occurs when a charged object comes into contact with a neutral object, and the charge is transferred between them. For example, rubbing a balloon on your hair causes the balloon to become negatively charged.
2. Charging by conduction: This involves transferring charge to an object by bringing it into contact with a charged object. The charge is evenly distributed across the object's surface. For instance, touching a charged object with a neutral conductor like a metal rod will transfer charge to the rod.
3. Charging by induction: This method involves the creation of a temporary charge imbalance in an object. By bringing a charged object near a neutral object, the charges in the neutral object redistribute, resulting in opposite charges being attracted or repelled. This can be seen when a negatively charged object is brought close to a neutral conductor, causing the charges in the conductor to separate and create a temporary charge separation.

Answer 2

There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another. ... Friction is useful for charging insulators, which are materials that aren't good conductors.
