5. Linear power supply Use lecture 2.1 to design an unregulated power supply (that is no regulator) that will deliver a minimum of 12 V with a maximum of 1 V ripple when the current supplied to a load is 50 mA. Use a half wave regulator. Determine a value for the capacitor. What is the output of the transformer's secondary in rms.

At x-values where g is positive, G should be increasing • At x-values where g is increasing, G should be positive . Any value of G can be determined by the formula G(X) = 1+Sg(t) dt. This formula will tell us the net signed area of the G graph at a given x- value.
