Question

Problem 4 Part 1: Left diagram. A hobbyist wants to use a microcontroller to turn a lamp on and off. The hobbyist finds a lightbulb that has a rating on it saying "max 100W at 12V" and inserts it into the lamp. So the hobbyist grabs a wn. Unsure of RI = İkSin the circuit as shown. Assuming the microcontroller can output 5mA, calculate how much power is delivered to the light bulb. You can assume the lightbulb acts lie NPN transistor with p1 90 and connects a power source with V2 12V to the lightbulb as sho a resistor. V. R, R, Microcontroller Microcontroller NPN #2 #1 Part 2: Right diagram. The hobbyist is sadly disappointed at how dark the lamp is. So the hobbyist adds a transistor (#2) to the setup as seen in the diagram on the right. Size the value so that lightbulb has the maximum amount of power through it.
