Current Electricity Question 1
Question 1 - 2024 (01 Feb Shift 1)
The reading in the ideal voltmeter $(\mathrm{V})$ shown in the given circuit diagram is :
(1) $5 \mathrm{~V}$
(2) $10 \mathrm{~V}$
(3) $0 \mathrm{~V}$
(4) $3 \mathrm{~V}$
Show Answer
Answer: (3)
Solution:
$\mathrm{i}=\frac{\mathrm{E}{\mathrm{eq}}}{\mathrm{r}{\mathrm{eq}}}=\frac{8 \times 5}{8 \times 0.2}$
$I=25 \mathrm{~A}$
$V=E-i r$
$=5-0.2 \times 25$
$=0$
