The things that are required by current to flow from main board to bulb,are as follows -
• Closed circuit : The current mandatorily needs a fault free closed circuit to flow from the main board to the bulb.
If there is any obstacle in the flow path of the current,the current will be not able to flow towards the bulb.
• Potential difference : The current mainly flows from higher electrical potential region to the lower electrical potential region.
The difference the higher potential and lower potential,is directly proportional to the amount of current flow in the circuit.
