Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). The rubbing of certain materials against one another can transfer negative charges, or electrons.

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

When two positively charged objects are brought near each other, a similar repulsive force is produced. When a negatively charged object is brought near a positively charged object, an attractive force is produced. Since both leaves are negatively charged, they repel each other.

Yes, when the charge on one body (q1) is much greater than that on the other (q2) and they are close enough to each other so that force of attraction between q1 and induced charge on the other exceeds the force of repulsion between q1andq2.

When two objects with opposite charges come close to each other, there is a sudden flow of electricity between them. For example, when two clouds with unlike charges come close to each other, a very heavy current passes through the air; this results in lightning.

When oppositely charged clouds comes near to each other,charge gets accumulated in large numbers and air present no longer resists their flow. Negative and positive charges meets producing streaks of bright light called lightning.

Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

That’s right, a banana. Supposedly all you need is a USB cable, some paper clips and three bananas to give your phone some juice. This video shows that if you connect three bananas with paper clips, and ‘plug’ your USB charger into the fruit, it will charge your phone.

Charging your phone while on the road could drain your car’s battery, too. If you leave your car running on “accessory” — where your engine is off, but you still use the radio — the device will draw power from your car’s battery as it charges.

Even though there is no risk of overcharging with the use of a high quality charger, the battery should not remain connected to the charger for more than 24 hours. A full charge is usually achieved by charging overnight. Even after a deep discharge, some chargers enable at least partial reconditioning of the battery.

Plugging your phone into a car’s USB port could stall the charging and even damage the charger. Charging your phone could even drain a car’s battery, especially if it’s an older model. The best thing to do is to get home to charge your phone at an outlet.

Charging My iPhone Overnight Will Overload the Battery: FALSE. Once the internal lithium-ion battery hits 100% of its capacity, charging stops. If you leave the smartphone plugged in overnight, it is going to use a bit of energy constantly trickling new juice to the battery every time it falls to 99%.

Is it bad to charge my phone to 100 percent? It’s not great! It may put your mind at ease when your smartphone’s battery reads 100 percent charge, but it’s actually not ideal for the battery. “A lithium-ion battery doesn’t like to be fully charged,” Buchmann says.

The myth about overcharging your phone is a common one. So it’s perfectly safe to charge your phone overnight, just make sure it doesn’t suffer from overheating. That said you’ll be surprised how quick phones can charge today, so you don’t really need to leave it charging for 8 hours.
