battery terminal end

For a current to flow through a conductor, a difference in charge should be maintained between the two ends of the conductor. To ensure this, a cell or a battery is used. The cell or a battery converts its chemical energy into electrical energy thus maintaining a cons..

At the terminal end of mRNA chain there is a stop, or terminator codon (UAA, UAG or UGA). It is not joined by the anticodon of any tRNA amino acid complex. Hence, there can be no further addition of amino acids to the polypeptide chain. The linkage between the last tR..

The two metallic conductors in the form of rods dipped in the electrolyte and connected to the two terminals of the battery are called electrodes. The anode is the electrode connected to the positive terminal of the battery. The cathode is the electrode conn..

As said earlier, in the metals some of the electrons are not so tightly bound to the atoms. They drift in all directions. The free electrons in a wire XY will not flow in a particular direction unless they are forced to do s..

Melde's electrically maintained tuning fork consists of a large tuning fork (F) made of a ferromagnetic alloy, whose shank is rigidly clamped to a heavy rectangular wooden board (W). A bent strip of a metal is attached to one of the prongs of the fork and this serves as a spring. This metal piece i..

(a) A car has a fresh storage battery of EMF 12V, internal resistance 5.0 x 10 - 2 W . If the starter motor draws a current of 90 A, what is the terminal voltage of the battery when the starter is on? (b) After a long use, the internal resistance of the storage h..

A car has a fresh storage battery of EMF 12V, internal resistance 5.0 x 10 - 2 W . If the starter motor draws a current of 90 A, what is the terminal voltage of the battery when the starter is o..

(a) The terminal voltage V (the voltage drop across the terminals of the battery) is related to the EMF of the battery (open circuit voltage drop) by the relation, V = E - Ir Now, E = 12 V, I = 90 A or V = 12 - 4.5 = 7.5 V (b) The maximum current from a ..

Telephone Circuits - Two-way operation is essential for satisfactory telephone service, and many of the problems of the industry arise from this fact. A simplified circuit for obtaining two-way operation is shown in the below figure. This is called a local-battery system because a separat..

Let us consider two resistances 'R 1 ' and 'R 2 ' connected in series. A battery of 'V' volts is applied to the ends of this series combinatio..
