DIRECT CURRENT AND ALTERNATING CURRENT

Olusola

Direct current (DC)

The Direct current (DC) is simply electric current that flows in one direction. It usually flows from a battery source. It also means electric current with one polarity of current or voltage.

Uses of DC

DC is often used to power low voltage appliances such as flashlights, toothbrushes, calculators, telephones and so on, although it can also power high voltage appliances.

Sources of Direct Current Supply

 Common sources of DC supply includes solar cells, batteries and DC generator.

Drawback of Direct current (DC)

The major drawback of Direct current (DC) is that it cannot be transmitted through long distances without considerable power loss. The power plant or source of direct current (DC) supply must be within 3km of the appliance which implies that direct current power plant/supply must be installed in every household.

Alternating Current (AC)

 Alternating current rapidly changes in direction. AC is transferred at very high voltage (kilovolts) over long distances and then stepped down with a transformer to between 100-240 volts at point of use.  

Uses of AC

AC is often used to power appliances that require higher voltages examples include fans, air conditioners, cookers, tvs ,  water heaters, pressing irons and so on

Advantage of Alternating Current

The major advantage of AC is that it can travel hundred to thousands of kilometers without considerable power loss making it possible for the location of central alternating power supply stations far from point of use.

Comparing Alternating to Direct Current

It can be argued that AC holds no practical advantage over DC. As stated earlier, DC is preferred over AC for low voltage appliances while AC is preferred to DC for high voltage appliances. However it is possible to build power supply/distribution systems that are more efficient with AC than DC and this is one reason why the AC is far more popular.

Some Safety Driving Advice

Olusola

Driving is a serious business; any mistakes could result in serious injury or even death. Good driving is a skill, you learn the first part at driving school and the other part during your driving experience.

Before Driving.

Check that your car is in perfect condition before driving, open the bonnet, check the level of engine oil on dipstick and confirm it is ok, check brake fluid level and also confirm it is ok, if either engine or brake oil is inadequate, you must refill before you start or move your car. Open the radiator and fill up with water if necessary, ensure no leakage of oil under the vehicle, check the tires, make sure they have adequate pressure and ensure that the nuts are tight.

Other things you should check before driving but not critical, include head lambs, brake lights traffic turning signals and horn; if any is malfunctioning, it should be repaired at your earliest convenience. If road safety officials stop your car and realizes any of these aren’t working, you may be fined

It is a good practice to put on your seat belt and put your phone on hands free mode before driving. Don’t drive under the influence or if you are sick.

During Driving.

Safe driving should be part and parcel of your daily driving habit. Always drive at safe speeds and distance from the vehicle in front of you, be patient and use your turning signals when negotiating a turn. Use the rear and side view mirrors to see what is around you. Anticipate mistakes that co- drivers and pedestrians can make in advance and take precautionary steps to avoid them.

Treat pedestrians with respect when driving, on a road with high population of people, drive slowly and use the horn. Remember a hit of your car on a pedestrian can result in you spending a lot of money on treatment, manslaughter charges or jail term.

When driving at night, or very dusty or foggy weather always use the headlamps and fog lights when necessary. To reduce glare when driving at night use the head lamps at low beam. Use high beam and fog lights during heavy rains.

When parking

Always park your car in a way it doesn’t obstruct traffic, don’t park in areas where your car is in danger of being hit. Engage the hand brakes when parking to prevent the car from moving. When bringing the car to a stop on a slope; in addition to engaging the hand brake put the gear in one or reverse or parking gear if your car uses automatic transmission.
