Question

find the current passing through 1/2ohm resistance in the fig. ​

Answer 1

Explanation:

current = V / R

So , Resistance = 1 /2 ohm

&. V= 1v

so, I = 1/2 /1

I = 1/2 A

Answer 2

Answer:

The current passing/flowing through the $\frac{1}{2}$ Ω resistor is $1$ $A$.

Explanation:

• The voltage is the same across both $1$ Ω resistors.
• The current in the $\frac{1}{2}$ Ω resistor is the sum of the individual currents in the $1$ Ω resistors.

The formula for equivalent resistance for two resistors that are connected parallel to each other is:

$R_{eq} =\frac{(R1\times R2)}{R1 +R2}$

where $R1,R2$ are individual resistors

As the $1$ Ω resistors are in parallel combination.

The equivalent resistance of this circuit, $R=(\frac{1 \times 1}{1 + 1} ) + (\frac{1}{2} ) \Omega$

                                                                        $= 1$ Ω

The battery voltage, $V= 1$ $V$

The current in the $\frac{1}{2}$ Ω resistor $=\frac{V}{R}$

                                                   $=\frac{1 V}{1\Omega}$

                                                    $= 1$ $A$

So, the current passing through the $\frac{1}{2}$ Ω resistor is $1$ $A$.
