GEOLOGY

Detailed explanation-1: -DC, or direct current, means the electrical current is flowing in only one direction in a circuit. Batteries are a good source of direct current (DC).

Detailed explanation-2: -DC stands for ‘direct current’ which means the current only flows in one direction. Batteries and electronic devices like TVs, computers and DVD players use DC electricity-once an AC current enters a device, it’s converted to DC. A typical battery supplies around 1.5 volts of DC.

Detailed explanation-3: -The current obtained from a battery is direct current and it flows from the positive terminal to the negative terminal of the battery through an appliance. Its magnitude and direction remains constant with time.

Detailed explanation-4: -Since AC is much better than DC for long-distance transmission, the power grid uses AC. Likewise, most of your home appliances use AC. However, solar panels produce DC power, and that’s also how most batteries store it.

Detailed explanation-5: -DC is the simple positive-and-negative type of electricity that you probably experimented with in 7th grade science. A key advantage is that it is easy to store in batteries. That is why portable electronics – flashlights, cell phones, laptops – use DC power; they have to store it.
