Advantages and Disadvantages of Direct Current

The main advantage of direct current is it is low resistance, it require less conductor and insulation material, can store electricity, No advancement in the circuit, and no reactive power is generated. However, the main drawback of Direct current(DC) is that it is difficult to current interruption, has Difficult voltage conversion, and is less efficient.  Electricity with direct current(DC) always flows in the same direction. Both the voltage and the polarity are constant, they don't fluctuate between positive and negative. In this blog post, we will discuss the Advantages and disadvantages of DC current to better understand this topic.

Advantages or Benefits of Direct Current

  • Direct currents (DC) are most suited for electronic circuits because of their constant nature. All electronic devices therefore require a DC source to function.
  • Renewable energy sources including hydropower, wind, and sun can all be used with direct current.
  • Because alternating current(AC) have peak voltage, they require less insulation than Direct current(DC) systems with the same voltage level.
  • For Short distances, Direct current(DC) distribution and transmission are less expensive than Alternating current(AC) distribution and transmission.
  • As it is compatible with power distribution systems and appliances, alternating current(AC) is the typical electrical current in homes and commercial buildings. 
  • Energy storage is another advantage of direct current). Direct current is electrical energy that can be easily stored in a battery or supercomputer, whereas AC energy can't be stored.
  • Direct currents (DC) are extremely energy efficient as their magnitude and polarity are constant. When compared to direct current (DC) the AC(alternating current) energy efficiency decreases with time due to its fluctuating magnitude, power factors problems, and noise production.
  • Because there is no inductance or capacitance effect with the DC supply, DC circuits are very energy efficient, noise-free, and have low power loss.
  • Another advantage of DC current is it is used in components of electronic devices like computers, cellphones, and televisions that depend on DC electricity to operate correctly. 

Disadvantages or Drawbacks of Direct current

  • Compared to AC generators. DC generators are more complex, in actuality the communication issue prevents Direct current(DC) from being generated at very high voltages.
  • The cost of Direct current(DC) is higher than that of Alternating current(AC).
  • A small amount of the electricity is lost and wasted as heat results from long-distance electrical transit across wires.
  • Direct current (DC) is their more complex design, electrical machinery and gadgets powered by DC supplies such as DC motors and DC circuit breakers are more costly than those powered by AC supplies.
  • In high-voltage transmission, you are unable to increase the DC voltage level because the transformer is DC unworkable.
  • Another disadvantage of Direct current is it like electromagnetic induct and shunt resistance, cannot be applied in real-world situations because the induction and capacitance effects do not exist with DC supplies.
  • Another drawback of Direct current is that it is less efficient than AC for many applications, including use in electric generators.
