resistance is here in searis so we add all resistance the wire is 7 cm so we can calcilat like
diameter 7*2 = 14
total res. = 2*7*4 = 56 ohm
progamingcop:
Sorry the answer is wrong..
what is ans
Actually I am also trying
but the answer should be 44ohm
is there any option
ya 7cm is radius
7*2 = 14
14* 4 = 56 ohm
not 44
44 is perimeter
