Calculate the kesistatnce or the wire in the new situation.34. The electrical resistivities of three materials P, Q and R are given belowQR2.3 × 103 Ω m2.63 × 10-8 Ω m1.0 x 1015 Ω mh material will you use for making () electric wires (b) handle for soldering iron, and () solar cells ?Give reasons for your choices.Which material will you use for making (a) electric wires (b) handle for soldering iron, and (C) so |
|
Answer» (a) Q should be used as electric wire should have less resistance.(b) R should be used as with high resistance no current will flow through the handle(c) P should be used to have ideal condition for storing charge. |
