What is $\text{“conduction tester”?}$
✓
Answer
It is a simple device to test whether a given object is a conductor or an insulator its set up is shown in the Fig.
$\rightarrow $ To test whether a given object is a conductor or an insulator, we connect the two ends of that object to $A$ and $B$.
$\rightarrow $ If after connecting the object between $AB$, the bulb lights up, the object is a conductor and if bulb does not light up, the object is an insulator.
