A small bulb marked "6V 3W" is connected to a 3V power supply. What is its rated power? What is its resistance? What is its actual current and power?
A small bulb marked with "6V 3W" is connected to 3V power supply. What is its rated power? What is its resistance? What is its actual current? What is its actual power?
It's better to list all the formulas

R=U^2/P=12
The resistance of the bulb is constant and the power is only related to the applied voltage
P actual = u actual ^ 2 / r = 0.75w
