I have a very basic breadboard circuit with a 1.5 (reads 1.6) volt alkaline battery, and 10 Ohm, 1% resistor, (reads 10.1 ohms)

I will expand it with more components as I prove out steps in Ohms Law.

According to the law, I should be measuring 160 ma current. Instead I am getting 125 ma. I checked for any additional resistance in the components

but all check out OK. I am using a $100 digital multimeter.

Why am I not getting 160 ma?

Thanks
