Question

caluclate electric work done when a chatge of 25c flows through electric circuit at a potential difference of 80v​

Answer 1

$\large \underline \bold{Given :-}$

$\: \: \: \: \: \: \: \: \: \: \:$$\sf{Charge \: (Q) = 25 \: C}$

$\sf{Potential \: difference \: (V) = 80 \: volt}$

$\large \underline \bold{To \: Find :-}$

$\sf{Calculate \: \: the \: \: electric \: \: work \: \: done \: ?}$

$\large \underline \bold{Usable \: Formula :-}$

$\: \: \: \:$$\sf{V =\dfrac{W}{Q}}$

$\small \bold{Where \: ,}$

$\: \: \: \:$$\sf{V = potential \: difference}$

$\: \: \: \:$$\sf{W = work \: done}$

$\: \: \: \:$$\sf{Q = charge}$

$\large \underline \bold{Solution :-}$

$\sf{On \: Using \: above \: Formula -}$

$\: \: \:$$\small \bold{W = VQ}$

$\: \: \:$$\sf{W = 80\times 25}$

$\: \: \:$$\sf{W = 20\times 4\times 25}$

$\: \: \:$$\sf{W = 20\times 100}$

$\: \: \:$$\sf{W = 2000 \: Joule}$

$\: \: \:$$\small \bold{W = 2 \: Killo \: Joule}$
