A parallel combination of three resistance take a current of 7.5a from a 30v battery. if two of the resistance values are 10 ohm & 12 ohm, find the third?

current in 10 ohm =v/r
(i)= 30/10=3ampere
current in 12 ohm =v/r
(i)=30/12=2.5ampere
current in third resistance =7.5-(3+2.5)
=2ampere
resistance =v/i
(r)=30/2=15ohm
(i)= 30/10=3ampere
current in 12 ohm =v/r
(i)=30/12=2.5ampere
current in third resistance =7.5-(3+2.5)
=2ampere
resistance =v/i
(r)=30/2=15ohm
