ECE323 Basic Electronic Circuits Assignment 2

1. For the following circuit, find (a) the value of the current I, (b) the value of the voltage across each resistor, and (c) the power absorbed or produced in each element.

   

2. Find the value of the current I flowing into the node.

   

3. A light bulb sees a 3-A current for 20 seconds. The light bulb generates 3 kJ of energy in the form of light and heat. What is the voltage drop across the light bulb?

4. How much energy (in Joules) does a 60-Watt light bulb consume in six hours?
