Answer 1

✵Question:

What is the resistance of an automobile headlight through which 250 ampere flows when 12.0 volt is applied on it..?

✵Answer:

↬Given data as follows:

☛Current flowing = 250 A

☛ Voltage/ Potential difference = 12V

↬We know, the relation of V, I and R,

☛That is ohm's law...

$\huge{ \dag{ \boxed{ \bold{ \green{V= IR}}}}} \\ \\ \large{ \sf{ where....}} \\ \\ \large{ \sf{V= \: potential \: difference}} \\ \\ \large{ \sf{I = \: current \: flowing}} \\ \\ \large{ \sf{R = resistance}}$

✵To Find:

☛Resistance of the conductor.

$\large{ \sf{ \star{ \: by \: using \: formula....}}} \\ \\ ⇢\large{ \sf{12 = 250 \times R}} \\ \\ ⇢ \large{ \sf{R = \cancel{\frac{12}{250} }}} \\ \\ ⇢ \large{ \sf{ \boxed{ \purple{R = 0.048 \: ohms}}}}$

☛Resistance of the conductor would be 0.048 ohms.

✵So Final Answer:

$\huge{ \boxed{ \bold{ \red{ = 0.048 \: ohms}}}}$
