installment payments on your 11 Using the definition of current-charge relationship, the equation may be rewritten since: i= dq! n sama dengan e dt! t
Hence, the current stream within t1 and t2 time period is,

The adverse sign shows the current stream in the contrary direction according to electric impose. 2 . 12 Assuming the location of the metal surface is usually S, The mass in the nickel with depth g = zero. 15mm is usually m=ρ×d×S In the mean time, using the electro-chemical equivalent, the mass from the nickel may be expressed since m=k×I×t where I = σ × S. Equating the two expressions of the mass, the finish time is located: t sama dengan ρ × d / σ = 1 . twenty-four × a hundred and five s ≈ 34. some hour Section 2 . several Voltage installment payments on your 13 By definition of ac electricity, when a great charge techniques from high voltage to low voltage, its potential strength decreases. And so a is " +”, b is definitely " -”. In other words, uab=1V. 2 . 18 The current i(t) is defined as: & 3 0 < capital t ' 1 # my spouse and i (t ) = % " $0 elsewhere!
