Question

if two resistors of  4 Ω are connected in parallel what will be total resistance?​

Answer 1

$formula \: of \: total \: resistance \: in \: a \: parallel \: circuit \: \\ \\ = \frac{1}{r1 } \: + \: \frac{1}{r2} \\ \\ applying \: this \: formula \: \\ \\ \frac{1}{r \: total} = \frac{1}{4} + \frac{1}{4} = \frac{2}{4} \\ \\ total \: resistance = r \: total \: = \frac{4}{2} = 2ohms$
