Calculate the electric current passing through the circuit when
the key is closed
5x2-10V
1502​

Answer 1

The electric current passing through the circuit=0.33 A

Explanation:

Potential difference=V=10 V

$R_1=5 ohm$

$R_2=10ohm$

$R_3=15 ohm$

Three resistance are connected in series.

Therefore, the equivalent resistance=$R_{eq}=R_1+R_2+R_3$

Using the formula

$R_{eq}=5+10+15=30\Omega$

Current=$\frac{V}{R}=$

Where R=Resistance of circuit

V=Potential difference across the ends of  circuit

Using the formula

Current=$\frac{10}{30}=0.33 A$
