A wire of length L and radius r is fixed at one end. When a stretching force F is applied at free end, the elongation in the wire is l. When another wire of s
To solve the problem of finding the percentage change in resistance when a wire of length L and resistance R is stretched by 25%, we can follow these steps: 1. Understand the Initial Conditions: - The initial length of the wire is L. - The initial resistance of the wire is R. 2. ...

6 The ends of a metal resistance wire are connected to a battery of electromotive force ( e.m. f.)8.0V and negligible internal resistance, as shown in Fig. 6.1.8.0V resistance wire Fig. 6.1The power dissipated by the resistance wire is 36W.(a) Calculate:(i) the current in the ...
These trends were mainly due to the impact of planthoppers during pre-tillering stages and the length of exposure to the planthoppers. High nitrogen compromised IR62 resistance, particularly in tillering plants in the greenhouse study; however, high nitrogen did not increase planthopper biomass-density...
Strip inductance is another parasitic to be considered, resulting from excessive trace length and lack of ground plane. Equation 2 shows the formula for trace inductance. See Figure 6. (2) W is the trace width, L is the trace length, and H is the thickness of the trace. All dimensions ...
l=(FL)/(AY)=(FL)/(pir^2Y) because lprop(FL)/(r^2) (l2)/(l1)=(F2)/(F1)xx(L2)/(L1)((r1)/(r2))^2=2xx2xx((1)/(2))^2=1 l2=l1 i.e., increment in its length will be l.
