Direction indicator

As that which the electrical voltage is connected to the lamp direction indicator 7400 mOhm resistance when current of 1.6 A passes through it?

Correct answer:

U =  11.84 V

Step-by-step explanation:

$$\begin{gathered} R=7400\mathrm{/}1000={\displaystyle \frac{37}{5}}=7.4\mathrm{\Omega } \\ I=1.6\text{ A } \\ I=U\mathrm{/}R \\ U=R\cdot I=7.4\cdot 1.6=11.84\text{ V} \end{gathered}$$
