In this case, the image is formed in front of the retina. What would be the values of V /I ratios when the potential difference is 0.8 V, 1.2 V and 1.6 V respectively? , I am also having same mindset….. Wattage of each bulb = 1.5 W Wire ‘Y’ has greater resistance as it has more length than wire ‘X’.

The spectrum of white light has the colours violet, indigo, blue, green, yellow, orange and red (VIBGYOR).

Write S.I. 42.Name the physical quantity which is (i) same (ii) different in all the bulbs 62. Many thanks to all who have donated.

So, the capacity of the fuse that should be used for the electric iron is of the order of 10 A. (b) An electrical fuse is rated at 2 A. You can use black / blue pen to write the parts of the diagram but use a pencil only to draw the structure.

In series: Rest of the bulbs will not glow. Let V be the potential difference applied by cell across the ends of a wire. (c) An electric iron of 1 kW is operated at 220 V. Find which of the following fuses that respectively rated at 1 A,3 A and 5 A can be used in it. 31.

Using Ohm’s law, current through each resistor is, Class 10 Science Electricity Very Short Answer Type Questions [1 Mark] – Year 2009.

A torch bulb is rated 2.5 V and 750 mA.

Filed Under: Class 10, Electricity Tagged With: circuit diagram. It measures the current ‘I’. (a)(i) Ammeter reading in the second case is half of the ammeter reading Ohm's law states that under constant temperature, the current passing … increases heavily. Length becomes one-fourth of the original length and area of cross-section becomes four times that of original. Many of the class 10 students find it difficult to grasp the concepts of Physics. In this case, the image is formed behind the retina. (c) Kilowatt hour – Commercial unit of electrical energy Name the physical quantity that can be obtained from this graph. The combination is connected across a 440 V mains. (c) What is the commercial unit of electric energy? Plug the key.

(iii)Resistance oC length. (a) Find the value of R. Questions based on these diagrams from CBSE Class 10 Physics portion of Science subject, are often asked in the CBSE Exams. 41.Series arrangements are not used for domestic circuits.
