$R_1$ dissipates the larger amount of power.

Work Step by Step

We can write an expression for the power: $P = I^2~R$ Since the current is the same through each resistor, the resistor with the higher resistance dissipates more power. Since $R_1 \gt R_2$, then $R_1$ dissipates the larger amount of power.
