- Reaction score
Just remember to use P=v^2/R or P=I^2/R when its asks for power dissipated.
also remember that every resistor are the same so they all have the value of 38.4 ohms
Resistor in Series are added while Resistor in parallel are inversed than added.
and also know that current prefers the least resistive path... such in case of ( Closed Closed Open).
Now try to solve it by yourself . If you cannot understand than feel free to contact.
see solution 839 atView attachment 57678 When strain is increased,it implies that length decreases according to strain=extension/length
when length decreases,resistance also decrease according resistance=resistivityXlength/area,right?
Then how come the answer is E?Maybe i can't understand the question itself.Help please!!
Thanks in advance
