Solution
An electric current cannot pass through objects such as plastic scales, tester holders, etc., because these objects are bad conductors of electricity.
From the given figure, it can be observed that one terminal of the bulb is connected to a tester holder. A current will not flow through the circuit. Hence, the bulb would not glow.
