Answer:

in series, R1 + R2 = RT

6 + R2 = 10

R2 = 4

IN SERIES COMBINATION,

CURRENT REMAINS THE SAME.

IT = VT/RT

IT = 20/10

= 2A

I remains the same in series, hence

I1 = 2A

I2 = 2A

V1 = I R1

= 2 x 6

= 12V

V2 = I R2

= 2 X 4

= 8V

P1 = I2R

= 2 X 2 X 6

= 24 W

P2 = I2R

= 2X 2X 4

= 16 W

TOTAL POWER = P1 + P2

= 40W
