Answer 1

Formula for vC(t):
(1/C)*(1/(1000*2*PI))*(-cos(1000*2*PI*t) + 1)
Computed value for v(0.0005) in volts:
0.318310
Now let's see what we measure from the simulation: Run a 2ms transient simulation on the circuit above, measure the voltage at 0.5ms and enter the result below.

Measured value for v(0.0005) in volts:0.317
Estimated value for electrical energy stored at time 0.0005, in joules:0.0000502

First look at the black waveform, the voltage across the load. It's now relatively stable at around 10V, with a small 0.6V ripple (the positive and negative supply voltage variations about the average supply voltage). Looking the green curve, the current into the load resistor, we see that it's also relatively constant at about 200mA. Approximately how much power is being delivered to the load?

Power delivered to the load in watts:2
Average current supplied by bridge rectifier, in amps:0.205
