Question

A potential difference of 110 V exists across the terminals of an electric motor whose effective resistance is equal to 5.5 ohm. The current drawn by it is:

• A. $200A$
• B. $2A$
• C. $20A$
• D. $605A$

Answer 1

Answer: (C)

$20A$

$V=IR$
$I=\frac{V}{R}$
$=\frac{110}{5.5}$
$=\frac{11\times 100}{55}$
$\Rightarrow I=20A$
