The purpose of a circuit board holder is too help you to not use your hands as much as you usually do. And also in addition to a PCB holder a swively table vise like that.

To supply the bell, because the latter has a rated voltage that's lower than the mains.
why does have to short-circuit secondary wire of current transformer ?
The abbreviation, 'PT', stands for 'potential transformer' (in Britain, the abbreviation is 'VT', and stands for 'voltage transformer'). This, together with a 'current transformer', falls into a category of transformer known as 'instrument transformers'. A 'PT' or 'VT' is used to reduce a high voltage to a level of voltage that can be safely read, remotely, by regular a.c. voltmeters or to provide inputs to high-voltage protection relays, while electrically- isolating the secondary circuit from the high-voltage primary circuit for the purpose of safety.
what is the function of transformer in the half wave rectifier circuit
The purpose of the common wire transformer in an electrical circuit is to step up or step down the voltage to the desired level for proper functioning of the circuit components.
The purpose of conducting sc (short circuit) and oc (open circuit) tests on a single-phase transformer is to determine its equivalent circuit parameters, such as the winding resistance, leakage reactance, and magnetizing reactance. These tests help to evaluate the transformer's performance and efficiency under various operating conditions.
To conduct electricity and allow the flow of current to the components on the circuit board.
As you have given NO details of the transformer,this is impossible to say.

Helps with the starting of large electric motors.AnswerAn autotransformer is a transformer with a single winding, rather than two separate windings. It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.

A motherboard (also called mainboard, main circuit board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. ... Motherboard means specifically a PCB with expansion capabilities.
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
