Direct current (DC) is the flow of electric charge in only one direction. Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidally, the circuit is known as an alternating current circuit.
What is the difference between DC and AC?
In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
What is AC and dc current PPT?
Direct Current (DC) • Direct Current is a flow of charge that always flows in one direction • A DC current is a current that does not change direction in time. Alternating Current (AC) • An Alternating Current (AC) current is a current that changes direction in time.
What is the alternative to PPT?
Top 10 PowerPoint Alternatives Compared. Some of the best PowerPoint alternatives include Prezi, Keynote, Slides, Slidebean, Zoho Show, Google Slides, Canva and, of course, Visme.
Why AC is dangerous than DC?
AC current is said to be more dangerous than DC current because the root mean squared value of AC is much more than its original value. Our heart is driven by electric pulses; the high electric frequency of AC current can affect the frequency of the heart and can lead to a heart attack.
What is meant by DC current?
Direct current (DC) is electrical current which flows consistently in one direction. The current that flows in a flashlight or another appliance running on batteries is direct current.
How is interrupted direct current produced?
Interrupted direct current (IDC) is used to describe continuous unidirectional current when it is interrupted to give pulses or phases of any duration, shape, or frequency. There are two types of long duration interrupted direct current: 1Rectangular wave pulses and 2Accommodation pulses.
Which software is used for presentation?
Keynote. Just as PCs are often loaded with PowerPoint, Macs come with Keynote, Apple’s presentation software. Like PowerPoint, Keynote is designed for creating slides, but it comes with the key advantages of visually stunning templates and a simple, clear interface.
What do you need to know about PowerPoint alternatives?
Any software that claims to be a PowerPoint alternative needs to qualify on several criteria. These criteria might not overlap, but as collective feature sets, they need to be able to accomplish basic tasks like creating and editing presentation slides.
What are the features of a presentation software?
Features: Rather than just including standard slides, software should offer alternative formats to share presentation content and engage audiences. Shareability: For easy collaboration, users should be able to share presentations with other users and allow simultaneous editing.
Which is the best app for nonlinear presentation?
If you want to make nonlinear presentation, you’ll find that Prezi is a great app for it. It’s simple to use, with an interface that keeps enough of the traditional slide layout to make you feel comfortable with it, while giving you the simple tools you need to format your text and more.
