Ile ladunku przeplynie w ciagu 5 s przez zarowke o oporze 500 Ω przy napieciu 220 V?

t = 5 s R = 500 Ω = 500 V/A U = 220 V q = ? [latex]R = frac{U}{I } ............. extgreater I = frac{q}{t} [/latex] [latex]R = frac{U}{ frac{q}{t} } = U * frac{t}{q} /* q[/latex] [latex]R * q = U * t /: R [/latex] [latex]q = frac{U*t }{R} [/latex] [latex]q = frac{220 V * 4 s }{500 frac{V}{A} } = 2,2 C [/latex] [ 1 C ] = [ 1 A * 1 s ]
