Answer Posted / Hemant Kumar Budakoti
The size of the cable required for lighting depends on the total power consumption and the voltage rating of the cable. Given that each LED tube consumes approximately 25 watts (assuming 4 feet = 120 cm and each tube has a power rating of 25W), and assuming a voltage rating of 230V, you can estimate the current draw using I = P / V. The total current required would be about 0.11 amps per LED tube, giving a total current requirement of approximately 2.2 amps. This is well within the capacity of a standard household wiring cable such as a single core PVC insulated cable with a cross-sectional area of 1.5mm^2 or larger.

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
