00:01
All right, so in this one, we're going to do problem number 50, like such.
00:08
All right, for this one, for the half -wave rectifier without a capacitor, the current is going to be zero for about half the time.
00:15
We approximate the average current as half of the full rms current.
00:20
All right, so if we're going to do that, so let's set this up.
00:24
So let's do an average current, okay, which should be equal to about one -half.
00:31
Oops, one half, and that'll be the voltage of the rms over resistance like such.
00:45
So let's substitute in.
00:47
So that was about 120 volts divided by 35 kilones like such.
00:58
All right.
01:00
Equal, after we plug and chug about 1 .75 mil amps.
01:05
And that's going to be our answer for part a.
01:07
All right, so this is just part a...
