A Person Is Manufacturing A House. He Bought 20 Ropes Of Wire Which Has A Density Of 300 Kg/m3.the Height Of The Building To Be Constructed Is 40 M. If The Capacity Of The Current Passed In The Wire Is 20 A And The Voltage Capacity Is 80 Volts.then What Will Be The Opposing Force To The Current If The Wire Is Used ?

Answer»

Explanation:

by OHMS law 

v = IR 

so R = v/i 

so r = 80/20 = 4
