What type of charging does NOT involve a transfer of charges? induction conduction grounding friction

## Step 1<br />The problem asks us to identify the type of charging that does not involve a transfer of charges. The options provided are induction, conduction, grounding, and friction.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### Induction<br />Induction is a method of charging an object by bringing it close to a charged object. This process does not involve a direct transfer of charges, but rather the redistribution of charges within the object.<br /><br />### Conduction<br />Conduction involves the direct transfer of charges from one object to another. This is typically done by touching the two objects together, allowing the charges to move from one to the other.<br /><br />### Grounding<br />Grounding is a method of charging an object by connecting it to the ground, which is considered to be a large reservoir of charges. This process does not involve a direct transfer of charges, but rather the redistribution of charges within the object.<br /><br />### Friction<br />Friction is a method of charging an object by rubbing it against another object. This process involves the transfer of charges from one object to the other.<br /><br />## Step 3<br />Based on the above analysis, we can see that induction and grounding do not involve a direct transfer of charges, while conduction and friction do.
