My son had this assignment and it is totally confusing to me.
This is the info provided:
and 3 batteries that are 1.5 V each
Knowing Ohm's law: voltage (in volts) =current (in amps) x resistance (in ohms) or V=IR. Determine in which circuit the voltage was the largest and explain how you know this?
I am drawing a blank and am assuming that the circuit with all three batteries would provide the most since they have the full power then. I am not sure about this and don't know does this mean he needs to figure out what the V=IR is?
