What is difference between ac and DC bulb?

AC bulbs are designed to be used with alternating current, which constantly changes direction. DC bulbs are designed to be used with direct current, which flows in only one direction. Therefore, the internal workings and design of AC and DC bulbs are different.


What are the key differences between alternating current (AC) and direct current (DC)?

Alternating current (AC) and direct current (DC) differ in the direction of flow of electric charge. AC changes direction periodically, while DC flows in one direction continuously. AC is used for long-distance power transmission, while DC is used for electronic devices and batteries.


What are the key differences between AC and DC current, and how do these differences impact the efficiency of electrical systems?

AC (alternating current) and DC (direct current) differ in the direction of flow and voltage fluctuation. AC changes direction periodically, while DC flows in one direction. AC is more efficient for long-distance transmission due to lower energy loss, but DC is better for certain devices like electronics. The choice between AC and DC depends on the specific application and efficiency requirements of the electrical system.


Which type of electrical current, AC or DC, is more dangerous?

Both AC and DC electrical currents can be dangerous, but AC is generally considered to be more dangerous than DC. This is because AC can cause muscles to contract involuntarily, making it harder for a person to let go of a live wire. DC, on the other hand, typically causes a single muscle contraction, making it easier for a person to release the source of the shock.


Is DC safer than AC in terms of electrical systems?

DC is generally considered safer than AC in terms of electrical systems because DC does not cause the same level of electric shock and is less likely to start fires.
