I'm guessing that the question refers to current or power.

Let's first calculate the combined resistance: for resistors in parallel 1/Rt = 1/R1 + 1/R2 + ...

So here 1/Rt = 1/17.2 + 1/22.3 = 0.103, so Rt = 9.7 Ω

Applying Ohm's law: I = V/R = 43.8 / 9.7 = 4.5(2) A

Or

P = IV = 4.52 x 43.8 = 198.0 W
