Question

what is the difference between direct current and alternating current write five difference

Answer 1

HEY MATE ❤️❤️❤️ HERE IS UR ANSWER IS...

DIFFERENCE BETWEEN ALTERNATING CURRENT AND DIRECT CURRENT.....

Loss
DC transmission loss, it is not suitable for long-distance transmission,
AC transmission loss is small, so suitable for long-distance transmission,

Use
DC voltage stability, no big noise, it is suitable for the use of electronic products. (such as televisions, radio computers, etc.)
AC power to go through the rectifier/switching power supply into DC power can be used for electronic products.

Measure the difference between 12V AC and DC:
A) with a digital universal measurement, respectively, with 20V AC voltage and 20V DC voltage file measurement, the results will be different.
B) simple measurement method: with a stylus pen (non-ordinary pen) on the wire foreskin, 12V AC will still show, 12V DC no display.

Safety
12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%.

Peak
According to the voltage pattern, 12V AC and DC instantaneous peak voltage is not the same, the instantaneous peak voltage (12V straight) ≡ 12V, instantaneous peak voltage (12V AC) = √2 × 12V

Conversion
2V AC to 12V DC: Simple (Diode Capacitor Regulator)
12V DC to 12V AC: Complex (Starter )
12) Use – most can think so (for most equipment):
12V DC device 12V AC power supply (burn equipment)
12V AC equipment 12V DC power supply (equipment use efficiency is reduced)

Answer 2

DC current

• the current flows in one direction
• the current which we get from a cell or a battery is direct current

• radios and television work with DC current

AC current

• the current which reverses direction after equal interval of time
• the alternating current produced in india reverses its direction every 1/100 sec
• lamps and kettles work with AC current.
