##### Reference no: EM1344498

Q1. Resolve the forward current If and voltage across at the 1k ohms load using practical and complex diode model. When rd=15 ohms and battery is 7V.

Q2. Radioactive decay of granite and other rocks in the Earth's interior provides sufficient energy to keep the interior molten, heat lava, and supply warmth to natural hot springs. This is due to the average release of about 0.030 J per kilogram each year. How many years are required for a chunk of thermally insulated granite to increase 340 °C in temperature (assume the specific heat of granite is 800 J/kg °C)?
