<p><span style="font-size:14px">Given, </span></p>

<p><span style="font-size:14px">⇒ R<sub>1</sub> = 10 Ω, R<sub>2</sub> = 20 Ω, and Potential difference (V) = 10 V</span></p>

<p><span style="font-size:14px">We know that in parallel combination, the reciprocal of total resistance is;</span></p>

<p><span style="font-size:14px">⇒ 1/R = 1/R<sub>1 </sub>+ 1/R<sub>2</sub> </span></p>

<p><span style="font-size:14px">= 1/10 Ω + 1/20 Ω </span></p>

<p><span style="font-size:14px">= (2 + 1)/20 Ω = 3/20 </span></p>

<p><span style="font-size:14px">Total resistance, R = 20/3 Ω </span></p>

<p><span style="font-size:14px">Now, electric current through the circuit, I = V/R</span></p>

<p><span style="font-size:14px">Or, I = 10V ÷ (20/3) Ω = 1.5 A</span></p>

<p><span style="font-size:14px">Electric current (I) through the circuit = <strong>1.5 A</strong></span></p>
