Formula for charge current and time

WebLet’s apply the equation for capacitor charging into some practice. Find the time constant 𝜏 for the RC circuit below. We can use the time constant formula above, where 𝜏 = R x C, measured in seconds. Hence, the time constant is 𝜏 = R x C = 47kΩ x 1000uF = 47s. a) Calculate the capacitor voltage at 0.7 time constant. WebSince we measure the charge in coulombs and time in seconds, therefore the unit of electric current is coulomb/Sec or amperes. The amperes is the SI unit of the electric current. The symbol for electric current is I. Thus, …
