Homework Equations
p = vi
v = ir
KVL
KCL
The Attempt at a Solution
Tried using KVL and KCL in various ways. This book gives horrid examples.
calcuseless said:I found the current in the last loop to be .4 A. Using V = IR to solve to get the voltage, I get 4.8 V at the 12-ohm resistor. I then used P = VI to get a power of 9.6 W, but the book has 1.92 W. Did I do anything wrong or is the book wrong again?
Simple circuits are electrical circuits that contain a power source, wires, and a load (such as a light bulb). They work by allowing electricity to flow from the power source through the wires and into the load, which converts the electrical energy into light, heat, or motion.
Yes, simple circuits can be built by anyone, regardless of their level of intelligence. They only require a basic understanding of electricity and some simple tools, such as wires, batteries, and switches.
The purpose of a simple circuit is to control the flow of electricity and create a desired effect, such as lighting a light bulb or powering a device. They are used in everyday objects, such as household appliances and electronic devices.
Yes, there are different types of simple circuits, such as series circuits, parallel circuits, and combination circuits. Each type has a unique way of connecting the components and affects the flow of electricity in different ways.
Some common mistakes when building a simple circuit include using incorrect components, not following the correct wiring diagram, and not properly connecting the components. It is important to double check all connections and use the correct components to ensure the circuit functions properly.
