The current flows in only one direction and it is mostly used in low voltage applications. The resistor is the main component of the DC circuit. A simple DC circuit is shown in the figure below which contains a DC source battery , a load lamp, a switch, connecting leads, and measuring instruments like ammeter and voltmeter.
The load resistor is connected in series, parallel or series-parallel combination as per requirement. The DC electric circuit is mainly classified into three groups. The circuit in which have DC series source, and the number of resistors are connected end to end so that same current flow through them is called a DC series circuit. The figure below shows the simple series circuit. In the series circuit the resistor R 1 , R 2 , and R 3 are connected in series across a supply voltage of V volts.
The same current I is flowing through all the three resistors. And the power factor of the DC voltages always remains 1. The polarity of the AC voltage always varies with time, and the polarity of the DC voltage always remain constant.

The AC voltage is unidirectional, and the DC voltage is bidirectional.
The term amplitude means the maximum distance covered by the oscillation and the vibrating body. Mechanism to switch back and fourth 90 degrees? Save my name, email, and website in this browser for the next time I comment. Direct Current DC Direct current is a bit easier to understand than alternating current. Is Amazon actually giving you the best price?
Ano ang pinakamaliit na kontinente sa mundo? DC is the Direct current in which instantaneous voltage is constant over the time and does not change so the frequency is termed as zero frequency. Learn about a little known plugin that tells you if you're getting the best price on Amazon.
When the electricity is negative, the diode allows it to flow down the negative wire but blocks the positive wire. Your email address will not be published. So, auto enthusiasts might be curious to know whether the car battery AC or DC. Mains electricity is an AC supply. The power factor for AC voltage lies between 0 to 1.
A power supply delivers electricity to one or more electrical loads. This makes the output of the power supply smoother when used on a device that uses radio frequencies. Alternating current is when the electricity flows one way and then back again over and over.

An easy way to think about a DC power battery is as a water feeder for a pet rabbit or hamster.
DC power products work similarly to this concept — once the electricity is drained in a battery, it can no longer provide power.
