An ideal battery sends a current of 5A in a resistor. When another resistor of value 10Ω is connected in parallel, the current through the battery is increased to 6A. find the resistance of the first resistor.

Answer:- R1​=R, i1​=5A

R2​=10+R10R​, i2​=6A

Since probable constant,

i1​R1​=i2​R2​

⇒5×R=10+R6×10R​

⇒(10+R)5=60

⇒5R=10⇒R=2Ω
