IGCSE Grade 10 Science Combined resistance of two resistors in parallel
|
\\(\\textrm{Resistance is a measure of the opposition to current flow in an electrical circuit.}\\)
\\(R_{eq}=\\Large \\frac{R_1 R_2}{R_1 \\normalsize + \\Large R_2}\\)
\\(1/R_{eq} = 1/R_1 + 1/R_2 + 1/R_3 + …… + 1/R_n \\)
\\(\\mathrm{ 1/R_{eq} = 1/R_1 + 1/R_2 + 1/R_3 +...}\\\\ \\mathrm{R_{eq}=R_1+R_2+R_3+..... }\\)
\\(\\textrm{When resistors are connected in parallel, the total resistance is less}\\\\ \\textrm{than the resistance of any individual resistor.}\\)
The voltage across each resistor is the same for resistors connected in parallel.
\\(R_{eq}=\\Large \\frac{R_1 R_2}{R_1 \\normalsize + \\Large R_2}\\)
\\(R_{eq}=\\Large \\frac{R_1 R_2}{R_1 \\normalsize+ \\Large R_2}\\)
