Electrical Engineering and Electronics In the parallel circuit of Fig. The basis of this law is this: Determine the value of Rs and RI, in the network of Fig. A positive teraja will confirm out assumption whereas a negative one will. In the present case, there is no flow of positive charge as such from one electrode to another. The two 4 a resistors are in series and are thus equivalent to an 8 a resistance. Find the currentjlowing through tetxbook 4 resistor in Fig.

Similarly, 3 A current can flow through its own closed circuit between A and C thereby producing a drop of 24 V across 8 0 resistor as shown in Fig. If the technooogy direction of current is not the actual direction, then on solving the quesiton, this current will be found to have a minus sign.

Let tOe be the temperature at which the minimum operating current of 0. When 6 a resistor is D B a b removed [Fig.


What is the resistance of the other coil? A galvanometer of 20 Q resistance is textgook across BD. This is shown in Fig. Voltage Divider Circuit A voltage electrkcal circuit also called potential divider is a series network which is used to feed other networks with a number of different voltages and derived from a single input voltage source.

Attached to the ends of the resistive element are metal caps which have axial leads of tinned copper wire for soldering the resistor into a circuit. Usually, they are produced as small rectangles having leads for being attached to printed circuit boards PCB.

The two givencurrentsourcesmaybe combinedtogetheras shownin Fig. Hence, according to the sign convention given in Art.

It is also called Thevenin voltage Vth. With reference to the network of Fig. I Didn’t Know That It is worth repeating that the additional tenn in the above Eq. Log In Sign Up. Elements like glazed tiles and actuate system of buildings etc. As seen, the two batteries have been connected in series opposition. A textbook of electrical technology: At node A, 3 amp incoming tedhnology 9 amp outgoing currents give a hechnology outgoing current of 6 amp.

With the help of Thevenin ‘s theorem, calculate flowing through the 3-Q resis- tor in the network of Fig.

When a voltage is applied, a constant drift velocity of 1. The 12 – V battery has been replaced by a short-circuit and the current source has been replaced by an open-circuit O. Determine the value of R and current through it in Fig. For this purpose, we will replace both the voltage and current sources. A copper conductor has its specific resistance of 1. About 82 per cent of the Indian population follows Hinduism and 15 per cent Islam and its plurality is visible in the four-fold varna system Brahmin, Kashtriya, Vaishya and Shudra and about 5, castes and sub-castes.

Many more questions are addressed in this book. It is denoted by the symbol J. ISBN and Cover design differs. Why are the two values equal? Calculatethe relativepotentialof pointA withrespectto that to B in Fig. After working for some hours the current falls to 0.

If technolovy cross-sectional area of the material is 1 cm2,calculate the magnitude of the current. What are the resistances of the first and third resistors?
