INTRODUCTION

Understanding power consumption is essential in designing and maintaining electrical systems. In this assignment, you will learn how to calculate amp load and power using the power equation. Since you have already learned about voltage, current, and resistance, this knowledge will help you ensure systems are operating within safe electrical limits.

OBJECTIVE

Practice calculating amp load and power using the power equation.

CALCULATING POWER

Power is required to run devices such as a light bulb, a motor, a sensor and many other electrical devices. It is very important to determine the total power required to power all devices on a circuit. If you don't have enough power than not all devices will work. So knowing how much power is required by the devices helps to know if you have sufficient power or if you need to upgrade your power supply to meet the needs of your devices. In this quiz you will be calculating power of devices to determine if the power requirements will work. Remember, you can always have more power supplied than what is needed. However, devices will not work if there is less power than was is needed.

The power calculations are shown below.
