MCQ
Calculate the potential difference between, points $A$ and $B$ and current flowing in $10\,\Omega $ resistor in the part of network below
- A$20 \,V, 2\, A$
- ✓$50 \,V, 1 \,A$
- C$40\, V, 1\, A$
- D$30\, V, 1\, A$
✓
Answer
Correct option: B.
$50 \,V, 1 \,A$
b
$15\,\Omega $ and $ 10\, \Omega$ are in parallel current through
$15\,\Omega $ and $ 10\, \Omega$ are in parallel current through
$10\, \Omega$ resistance $=\frac{\mathrm{V}}{\mathrm{R}}=\frac{10}{10}=1 \mathrm{\,A}$
$I=\frac{10}{2}=5 \,A$
$\mathrm{V}_{\mathrm{AB}}=\mathrm{IR}_{\mathrm{eq}}$
$=5 \times 10=50 \mathrm{\,V}$
