Question

Consider a circuit with two unequal resistance in parallel then

Answer 1

Answer:

when unequal resistors are connected in parallel in a circuit the largest current through it . the potential drop it always the same across each resiston

Explanation:

please mark me as brainliest

Answer 2

Answer:

In a circuit with two unequal resistance in parallel,

• Net resistance is = $\frac{rR}{r+R}$

• The voltage across both resistance remains the same.

• current in the resistance $r$ is given by, $i_1=i(\frac{R}{r+R} )$

• and current in the resistance $R$ is given by, $i_2=i(\frac{r}{r+R} )$

Explanation:

Let's say the two unequal resistance in the series are $r$ and $R$.

Net resistance in the series circuit will be,

$\frac{1}{R_{net}}=\frac{1}{r}+\frac{r}{R}$

$\implies R_{net}=\frac{rR}{r+R}$

we know that the voltage across the resistors in parallel is the same.

If the current across this parallel path is V then the voltage across both the resistance will also be V.

Let's say current $i$ come to this parallel path.

Then, the current in the resistance $r$ is given by, $i_1=i(\frac{R}{r+R} )$

and current in the resistance $R$ is given by, $i_2=i(\frac{r}{r+R} )$
