Question

A current of 0.4 A flows through a conductor for 5 minutes. How much charge would have passed through the conductor ?

Answer 1

$\huge{\underline{\overline{\mid{\bold{\red{AnSweR}}}\mid}}}$

$\bf\underline\red{Given \: -}$

$I = 0.4 \: A$

$t = 5 \: min = 5 × 60s = 300s$

$\bf\underline\red{Formula \: - }$

${Q = 1 × t }$

$Q = 0.4 \: A × 300s$

$\bf\underline\red{Therefore}$

$\bf\underline\red{Charge\: passing\: through \:the\: conductor }$

$\bf\underline\red{= 120\: C}$

Answer 2

we know that I (current) = q(charge)/t (time)firstly convert 5 minutes into seconds one minute is 60 secondsfive minute is 300 secapply the formula -0.4 = q/300

we know that I (current) = q(charge)/t (time)firstly convert 5 minutes into seconds one minute is 60 secondsfive minute is 300 secapply the formula -0.4 = q/3000.4×300 = q

we know that I (current) = q(charge)/t (time)firstly convert 5 minutes into seconds one minute is 60 secondsfive minute is 300 secapply the formula -0.4 = q/3000.4×300 = q120 c ( coloumb) unit of charge is coloumb
