Question

Find the value of ‘I’ for the following circuit.

• A. $1A$
• B. $10A$
• C. $\frac{1}{16}A$
• D. $\frac{1}{8}A$

Answer 1

The correct option is A

$1A$

Since all the resistors are placed in parallel combination, so the equivalent resistance of the system will become $\frac{1}{R_{eq}}=\frac{1}{140}+\frac{1}{140}+\frac{1}{140}+\frac{1}{140}$
$R_{eq}=\frac{140}{4}{R}_{eq}=35\Omega$
Now applying Ohm’s law $V=I\times R$
$I=\frac{V}{R_{eq}}$
$I=\frac{35}{35}=1A$
