Question

Two resistances of 5W,5Ware connected in parallel .the potential difference across the combination is 5V.calculate the current across each resistor

Answer 1

as the two resistances are connected in parallel, then their total resistance is given by;

1/r=1

Answer 2

Explanation :

It is given that two resistors of resistances $5\ \Omega$ are connected in parallel.

We know that in parallel combination the potential difference across the resistors remains the same while the current divides.

So, the equivalent resistance will be :

$R_{eq}=2.5\ \Omega$

According to Ohm's law :

V = I R

So, $I=\dfrac{V}{R}$

$I=\dfrac{5\ V}{2.5\ \Omega}$

$I=2\ A$

Hence, this is the required solution.
