Find the Load Resistance

Random numbersDIVHard

In the divider below, Vs=18 VV_s = 18\ \text{V} and R1=1 kΩR_1 = 1\ \text{k}\Omega. With no load, the output is vo=9 Vv_o = 9\ \text{V}. When a load RLR_L is connected across the output, vov_o drops to 8.471 V8.471\ \text{V}. Find RLR_L, in kilohms.

Answers within 2% are accepted. Units with SI prefixes work too, like 0.003 A or 3 mA. Use a minus sign for negative values.

Scratch work goes here. Draw with a mouse, finger, or stylus.
