Answer» tion:↙️↘️◆↙️↘️◆↙️↘️◆↙️↘️◆↙️↙️◆↘️↙️ ❤️_________✍️_________❤️Given that the power of bulb is 100W and operated at 200V POTENTIAL difference.We are all familiar with the formula i.e P=VI according to the given problem P=100W & V=200V. substituting in the above formula we get i=0.5 AMP.We also known that P=i^2R. substituting the required values in equation above, we get R as R=100/(0.5)×(0.5) i.e.R=10000/25 =400 ohmHence the resistance offered by the bulb is 400ohm✳️❇️✳️❇️✳️❇️✳️❇️✳️【◆】●【◆】●【◆】●【◆】●【◆】●【◆】❤️✨✨✳️✳️✳️✔️✔️✔️✔️➖➖➖➖➖follow me have a NICE n WONDERFUL day ❤️silentmunda ❤️ |
