Calculating the voltage across a capacitor.
The voltage, V, across a capacitor can be expressed as:
A 1.25F capacitor that has an initial voltage of 25.o V is charged with a current that varies with time as i = t (t2 + 6.83)1/2. Find the voltage across the capacitor at 1.00seconds.
Write the initial equation.
Now do the substitution for u, du, n.
u = t2 + 6.83 du = 2t dt n = 1/2
Now integrate:
