Difference between AC and DC?
Difference between AC and DC:
AC (ALTERNATING CURRENT)
1. AC is the type of electric current which varies instantaneously with time.
2. Suitable for long distance transmission as power losses are minimum.
3. Freqency Between 50 Hz to 60 Hz, different in different countries
4. Capacitor allows DC to pass thorugh it, thus capacitive impedance will be low.
5. High Voltage application such as home appliances, office equipments.
DC (DIRECT CURRENT)
1. DC is the type of electric current which remains constant with time.
2. Not suitable as power loss is directly proportional to distance.
3. Frequency of DC is zero.
4. Capacitor blocks DC, thus capacitive impedance will be infinite.
5. Low Voltage applications in electronic circuits

Difference between AC and DC?
So AC and DC... there u go..frnd!! well if the current flows always in the same direction it is called direct current..which is written as DC. The current obtained from a cell or a battery is DC...Note:- DC dynamo is a device which produces direct current.. coming to next part...if the direction of current changes after equal interval of time...it is called alternating current...which is written as AC...Note:- AC dynamo is a device which produces alternating current... hope this 1 is helpful!!!!
