Question

please give me answer​

Answer 1

Answer:

10√3

Explanation:

$\bf{\huge{\boxed{\rm{\orange{Hey Mate:}}}}}$

Power = P = VI = I²R

36 = I²(12)

I = √3

V = (√3 )*12 = 12√3 volts.

Net resistance of 18 & 36

= 18*36/(18+36)

= 18*36/54

= 12

Net resistance = 12*12/(12+12)

= 6

Voltage drop in 6 ohm = 12√3

So, I = V/R = 12√3/6

= 2√3

So, R = V/I = 60/2√3

= 30/√3

= 10√3

Answer 2

Power = P = VI = I²R

36 = I²(12)

I = √3

V = (√3 )*12 = 12√3 volts.

Net resistance of 18 & 36

= 18*36/(18+36)

= 18*36/54

= 12

Net resistance = 12*12/(12+12)

= 6

Voltage drop in 6 ohm = 12√3

So, I = V/R = 12√3/6

= 2√3

So, R = V/I = 60/2√3

= 30/√3

= 10√3
