Question

Current flowing through a conductor and the potential difference across its two ends are as per reading of the ammeter and voltmerer shown below. The resistance of two conductor could be
a) 0.02
b) 20.0
c) 0.024
d) 24.0

Answer 1

so given ma is 360 convert into a is 360into 10^-3
voltage is 7.2
as per the formula
R =V/I
=7.2/360into10^-3
= 20ohm
