Answer 1

Answer:

8E^2/R

Explanation:

All the 8 resistors are in parallel so their equivalent resistance will be R/8

Now power dissipated is given by

H=E^2/Reff

So,

H=E^2/(R/8)

H=8E^2/R

Answer 2

Explanation:

potential difference across each resistor connected in a ring are parallel.

thus, equivalent resistance of the combination is = R/8 ohm

power dissipated = V²/R = E²/ (R/8)

= 8E²/R option D.
