The Current Temple Puzzle Scenario: While exploring an ancient temple, you come across a chamber with a door locked by a unique mechanism. A current source, resistors, and a mysterious LED (which seems out of place for an ancient temple!) are part of this mechanism. An inscription states: "Illuminate the path by ensuring 2 volts across the ancient light." Components: 1. A current source /=3 mA. 2. Resistor R1=500 ohms. 3. Resistor R2=1 kohm. 4. A variable resistor Rv, adjustable from 100 ohms to 2 kohms. 5. An LED that you deduce will light up if there's exactly 2 volts across it. 6. A 5V source Configuration: • R1 is in parallel with the current source • This parallel combination is connected in series with the 5V source. The current direction in the current source is flowing away from the positive terminal of the 5V source • This is then followed by a parallel network comprised of R2 and the other branch containing the LED and Rv in series. • The parallel network is then connected in series to the negative terminal of the source Question: To what value should you adjust the variable resistor Rv to ensure there's 2 volts across the LED, unlocking the door?
