The ratio of the thermal energy dissipation by resistor 1 to that by resistor 2 will be 1 : 2

Resistors can be arranged in series or parallel

The resistors arranged in parallel will have the same potential difference across each every one of them.

Given that Resistor 1 has twice the resistance of resistor 2. They are connected in parallel to a battery. That is

= 2

Power P = lV

from Ohm's law

V = lR

Make l the subject of formula

l = V/R

Substitute l into power formula

P = / R

For the Resistor 1,

P = / 2

For the Resistor 2

P = /

The ratio of the thermal energy dissipation by 1 to that by 2 will be

/2 x /

The and the will cancel out.

Therefore, the ratio of the thermal energy dissipation by 1 to that by 2 will be 1:2
