Hello world

innovative project ideas on electricity

Every appliance surrounding you runs on electricity. Right from your lights, fans, refrigerator, mixer, and even charging your mobile phones, everything is powered by electricity. Electric Vehicles are gaining popularity and picking up momentum as we go.

What is electricity?

Electricity is the flow of electric charge. By converting natural sources of energy such as coal, natural gas, nuclear power and so on, we get electricity. To harness the energy from renewable sources, many towns were built around waterfalls. In the famous kite experiment by Benjamin Franklin, a kite was flown during the thunderstorm. He wanted to demonstrate that lightning had the same electric charge as electricity. To conduct this experiment, he needed a thunderstorm to prove his hypothesis. Unlike the popular misconception, Benjamin Franklin didn?t discover electricity, but through his experimentation, he found a connection between lightning and electricity.

While few people shared Franklin?s beliefs, not many supported him. He has expressed his thoughts about electricity in many letters which were appreciated by the scientists in London. These scientists published his work in a book ?Experiments and Observations on Electricity.?

 Here are five science projects for you to test electricity:

Static electricity experiment

Take a balloon and rub it on your hair. Now hold the balloon away from the hair, and you?ll notice that the hair is attracted to the balloon.

Take 2 inflated balloons. Start rubbing each balloon against a woollen fabric. Now hold each balloon by its string and move them simultaneously. Observe the reaction of the balloons. Both the balloons will drift apart.

Why does this happen? When you rub the balloons to a woollen fabric or the hair, it creates static electricity. The hair and fabric become positively charged as they have more protons than electrons. When you hold the balloon near the hair, it attracts the hair towards it as opposites attract. Similarly, since both the balloons are negatively charged, they repel each other as like repels like.

Bend water

Take a comb and rub it on your hair. Now hold this comb near water running from a faucet. You?ll notice that the flow of water appears to make room for an invisible force.

What causes the water to bend? Due to gravity, the flow of water was perpendicular to the ground. But when the comb is rubbed to the hair, static electricity is generated. When this negatively charged comb is held near the running water, it repels the water flow and bends the flow which seems almost magical.

Charge a toothpick

First, take a toothpick, measure the toothpick and mark its centre. Next, take a 5 rupee coin and make it stand on the table. Once you?ve managed to do this, take the toothpick and balance it over the coin. Make sure the centre of the toothpick touches the coin. Take a plastic cup and place it over the toothpick and coin. Take a balloon and rub it on your hair. This action will charge the balloon negatively. Now hold the balloon near the glass. The positively charged toothpick starts rotating at the top of the coin through the glass.

Built a circuit

Make a circuit with a copper wire, a 6-volt battery, some paper clips and a light bulb. Once the circuit is complete, touch the paper clips to the negative and positive sides of a battery, the bulb will light up. When you break the circuit by moving the paper clip away from the battery, the bulb will go off. Doesn?t it feel great to power your own bulb?

Sour lime battery

Take 1 copper coin and 1 silver-zinc coin and clean them with water thoroughly. Roll a sour lime to loosen the juice in it. Make two slits in the sour lime at a distance of one centimetre and insert the coins. Use a digital multimeter and measure the current in the circuit by touching one electrode to each coin. This is a simple voltaic cell. You can use any citric fruit for this experiment.
