Question

RESISTANCE OF A HEADLIGHT

What is the resistance of an automobile headlight through which 2.50A flows when 12.0V is applied to it?

Answer 1

Gives

Voltage=12.0 V

Current=2.50 A

Now we know that

$R=\frac{V}{I}\rightarrow(1)$

Eqution (1) put value

$R=\frac{12}{2.50}=4.8ohm$

$R=4.8ohm$
