What must be the potential difference across individual appliances

Term Meaning Battery Device that transforms chemical energy into electrical energy. An ideal battery has no internal resistance. Electric potential difference ( Δ V \Delta V Δ V delta, V ) Energy change per unit charge between two points. Also called voltage or electric potential. Has SI units of Volts V = J C \text V = \dfrac V = C J ​ start text, V, end text, equals, start fraction, start text, J, end text, divided by, start text, C, end text, end fraction . Electromotive force (EMF, ϵ \epsilon ϵ \epsilon ) EMF is the potential difference produced by a source such as an ideal battery. Has SI units of V \text V V start text, V, end text .

Current flow and electric potential difference can be better understood by using the analogy of a boulder rolling down a hill. At the top of the hill, the boulder has a lot of gravitational potential energy. Similarly, an electron has a lot of stored energy in the form of electric potential energy when it is at the negative terminal of a battery. The boulder will naturally fall toward the ground where potential energy is lower. The electron at the negative terminal of a battery will naturally flow to...

Whether you are renovating your kitchen or it is time to replace one or more of your appliances, you'll need to make a number of decisions about the size, features, energy efficiency, and cost of any new additions, as well as the finishes. Back in the days when harvest gold, avocado green, and burnt orange appliances were the norm, the rest of the kitchen was often color-coordinated with matching countertops, wallpaper, and cabinetry—but if we've learned anything from history it's that you can have too much of a good thing. As kitchens and appliances have evolved there are more color choices than ever before, and fortunately, there is no longer a need to choose just one. Read on to learn everything you need to know about successfully mixing appliance colors from the team of experienced professionals at Mr. Appliance®. Do Appliances Need to Match? If you've been asking yourself the question "Are mixed color appliances okay?", the short answer is, yes! Of course, there are exceptions to every rule including this one, and that is when mixing colors that are too similar but don't quite match. While you may read or hear conflicting information from a friend, designer, on the internet, or in print, home design is ultimately up to the homeowner, and mixing appliance colors can be a great way to express your personal style, create a focal point in your kitchen or laundry room, or add a pop of color to a neutral palette. Kitchen Appliance Trends While your kitchen appliances are a ...

A. The appliances are connected in parallel. B. The potential difference across each appliance should be same as they are connected in parallel. The potential difference between live and neutral wire in domestic wiring is maintained at 220 V in India. Hence, the potential difference across each appliance should be 220 V. C. No, the current passing through each appliance is not same. From Ohm's law, the current flowing through each appliance is given as `I = V/R` Since, potential difference across each appliance is same, thus `I ∝ 1/R` Now, each appliance has different value of resistance. Thus, the current flowing through them will be different. The one with greater value of resistance will receive lesser amount of current and the one with less value of resistance will receive more current. D. Domestic appliance are connected in parallel because this connection assures that even if one or more appliances get faulty or stops working, the working of others will remain unaffected. E. The working of other appliances will remain unaffected even if the T.V. stops working. The current through T.V. will stop but the other appliances will receive the approximately the same amount of current as before. This is because in parallel connection, the current divides itself in the number of electrical branches present. If one of the branches becomes open circuited due to some fault, the remaining branches will still be forming complete circuit for the flow of current.

The accompanying figure shows some electrical appliances connected in a circuit in a house. Answer the following questions. A. By which method are the appliances connected? B. What must be the potential difference across individual appliances? C. Will the current passing through each appliance be the same? Justify your answer. D. Why are the domestic appliances connected in this way? E. If the T.V. stops working, will the other appliances also stop working? Explain your answer. A.Appliances are connected in parallel. B.The potential difference across all appliances is same in parallel connection. C. No, as every appliance has a different load (resistance), the current flowing through each appliance will be different. D.The domestic appliances are connected in parallel as the potential difference remains same. E. No, the other devices will not stop working as thecurrent flowing through them is along different paths.
