    when two wires carrying current touches each other it causes short circuit

    1Thank You

    Ojasvi Nishad 5 years, 9 months ago

    Short circuit happens when two current carrying wires touch each other. This may usually happen if the insulation covering over the wire gets damaged by heating effect. Sometimes, incorrect wiring also leads to a short circuit.

    The rain water can be used to recharge groundwater known as rainwater harvesting. When rains comes the pipes connected to underground seeps down . This process is called infiltration.

    Tulika Kamra 5 years, 9 months ago

    Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). ... Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system. Tree roots increase water saturation into groundwater reducing water runoff.

    The electric current is passed through a high resistance wire the resistance wire becomes hot and produces heat. This is called the heating effect of current. The electric energy gets converted into heat energy. Greater the resistance of a wire greater will be the heat produced in it by a given current. The resistance depends on the length and thickness of the wire. Similarly, greater the magnitude of a wire greater will be the heat produced in it by a given current.

    Mirror

    Lens

    This works on the principle of reflection

    This works on the principle of refraction

    These are manufactured using materials other than glass or clear plastic

    These are manufactured using materials made up of glass or clear plastic

    An ideal mirror reflects 100% of light

    An ideal lense refracts 100% of light

    The uses of mirror can be seen in houses, automobiles, solar appliances etc

    The uses of lenses can be seen in astronomy and scientific industries, medical and research purposes etc.

    There are two types: concave and convex

    There are of six types of lenses

    Plane mirrors does not have a focal point

    It has two focal points for each kind of lense

    Electric current flows through the coil when the switch is ON, and the iron core acts as an electromagnet. The iron core attracts the hammer towards it. The hammer hits the bell and produces a sound. The circuit breaks at the screw contact when the hammer moves towards the iron core. At this point, the iron core ceases to be an electromagnet. The hammer is pulled back to its original position due to the spring action of the steel rod, and then touches the contact again to complete the circuit. The circuit is completed and current flows through the coil again, and the hammer strikes the bell again. The process repeats itself and you hear a ringing sound since the hammer keeps hitting the bell, until the switch is released.
