Answer 2

AnswEr:-

Your Answer Is 2 : 1.

ExplanaTion:-

Given:-

• Two Resistors of 10 ohm and 20 ohm respectively. (Say resistor A and B)

• Both resistors are connected in series with 5 volt battery.

To Find:-

• The ratio of current passing through both the resistors.

Law Used:-

Ohm's Law:-

$\tt\longrightarrow V = IR (by \: ohms \: law).$

$\tt\longrightarrow I = \dfrac{V}{R} .$

Where,

• V = Volts (Potential difference).
• I = Current.
• R = Resistance.

Now,

By using above formula:-

Current passing through 10 Ohm resistor:-

= V/R.

= 5/10 amphere.

= 1/2 A.

Similarly,

Current passing through 20 ohm resistor:-

= V/R.

= 5/20 amphere.

= 1/4 A.

Therefore,

↦ $\dfrac{\frac{1}{2}}{\frac{1}{4}}.$

= $\cancel\dfrac{4}{2}.$

= $\dfrac{2}{1}.$

So ratio of current passing through A : B,

= 2 : 1.

Therefore your answer is 2 : 1.
