10 Smart tips to study effectively

1) Find a good study spot .A place with a lot of distractions makes for a poor study area.A quiet place with no distraction would be good study place.

2) Take good Notes. Read through your materials slowly and write down key points. Write down any questions you have about the materials that you can later discuss with your classmates or course instructor.Quiz yourself on the material you have just read. If you struggle with certain questions, make not of these areas for additional study.Summarize the Main Points .Once you have studied the material, see if you can answer these questions: Can you identify the main concepts covere

Kinematics Good conceptual problems

Question: If you are riding on a train that speeds past other train moving in the same direction on adjacent train.It appears the other train is moving backward. Why?

Your reference frame is that of the train you are riding. If you are traveling with a relatively constant velocity (not over

Use of concept of electric potential

We already know about electric field and electric potential. We also know that electrostatic field is completely characterized by vector function E(r). The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. Now a question arises why do we need introduction of electric potential when we already have electric field for the description of electric force between charges.

What are light emitting diodes?

A LED is a forward biased P-N junction diode which emits visible light when energized.

A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

Capacitor : Uses, Unit and Formula

1) The main purpose of the capacitor is to store charge . If an instantanous strong current is to be flown in a circuit,the best way would be to connect the terminals of the circuit to a charge capacitor

2 A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
