The rechargeable battery used in a mobile phone hand set is usually:

Neha's elder brother purchased "I Phone 6 - Apple" mobile phone Rs. 65,000 without cash memo from one of his friend-an authorised dealer with a guarantee that the mobile phone will be replaced with a new one if any of its parts become defective within 1 year from the date of purchase. Within 1 month, the mobile stopped working. When Neha's brother approached his friend for replacement of mobile, he refused. Name the redressal agency under the consumer protection act where Neha's elder brother can file the complaint.

A capacitor of capacitance C is given a charge go. At time t = 0 , it is connected to a battery of emf E through a resistance R . Find the charge on the capacitor at time t .

A constant current exists in an inductor coil connected to a battery. The coil is short circuited and the battery is removed. Show that the charge flown through the coil aftter the short circuiting is the same as that which flows in one time constant before the short circuiting.

Rajni purchased a mobile phone and a refrigerator for Rs. 12000 and Rs. 10000 respectively. She sold the refrigerator at a loss of 12 percent and the mobile phone at a profit of 8 percent. What is her overall loss/profit? Los s of R s .280 b. Los s of R s .240 c. P rofi t of R s .2060 d. P rofi t of R s .2160 e. none of these

There is a conducting wire of length l and radius of cross section r. The number of free electrons per unit volume of the conductor is n and the mobility of electrons is mu . A battery of potential difference V is connected across its length. Find electric current flowing through the wire. Assume e as the magnitude of charge on electron.
