What are ac and dc powers and what are their differences
Answers
Answer:
The AC power isalternating current with periodical changes in voltage, current follow direction while the DC power is constant current with invariable voltage and current flow direction.
Explanation:
AC is alternating current meaning the current reverses its direction usually 50 or 60 times whereas DC or direct current travels only in one direction. AC overcomes resistance better and can be raised and lowered in voltage for transfer across the country.
difference between AC &DC
DC is a power source with fixed VOLTAGE. It has only one POSITIVE and one NEGATIVE terminal, like you car's battery (12 Volts) or any regular battery (1.2, 1.5, 3.7V…). Today most of them come from internal chemical sources, even being electrically rechargeable. AC is a power source with ALTERNATING VOLTAGE.
