An electrical circuit contains a resistor, component Y\text{Y}Y.
State the name of the measuring instrument used to measure the current passing through component Y\text{Y}Y, and state whether this instrument is connected in series or in parallel with component Y\text{Y}Y.
Component Y\text{Y}Y has a resistance of 15.0 Ω15.0\ \Omega15.0 Ω.
A current of 0.80 A0.80\text{ A}0.80 A flows through component Y\text{Y}Y.
Calculate the potential difference across component Y\text{Y}Y.
