Answer 2

Answer:

I = under root 6 ampere (current )

Explanation:

resistant 2 is in a parallel series

then equivalent resistance = R1R2/R1+R2

= 2×2/2+2 = 1 ohm

so now it is series

so resistance = 2+ 1= 3ohm

P = I square *r

18 watt = x^2 × 3 ohm

18/3 = x square

under root 6

current = under root 6
