An ideal gas is filled in a closed rigid and thermally insulated container. A coil of 1000 ohm resistor carrying current 1 A for 5 min supplies heat to the gas . The change in internal energy of the gas is The operating temperature of the filament of lamp is 2000∘C. The temperature coefficient of the material of the filament is 0.005∘C−1. If the atmospheric temperature is 0∘C then the current in the 100 W−200 V lamp when it is switched on is nearest to November 17, 2020 Category: Uncategorised (JEE Advanced Physics by BM Sharma + GMP Solutions) , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
