Of the two bulbs in ahouse, one glows brighter than the other. Which of the two has a larger resistance?

The voltage current variation of two metallic wires X and Y at constant temperature are a shown in the figure HQ. 7. Assuming that the wires have the same length and the same diameter explain which of two wires will have larger resistivity.

Draw two figures which has only one line of symmetry .

The volume of two spheres are in the ratio 64:27. Find the difference of their surfaces areas if the sum of their radii is 7 cm.

How is a wavefront defined? Using Huygens' prniciple draw a figure showing the propagation of a plane wave refracting at a plane surface separating two media. Hence verify Snell's law of refraction.

How does the collector current change in a junction transistor, if the base region has larger width?
