Vt = 20 Vrms @ 1 kHz turns ratio =2:1 R1 = 1 KΩ and C1 = 47 µF. What is Vp on R1?

 

[mneary]

forty two?

How are we supposed to help? Without a schematic your question is meaningless.

forty two?

20V*(1k/sec)*2*(1k*47U)sec=1880V.
That's my answer and I'm stickin' to it.

20V*(1k/sec)*2*(1k*47U)sec=1880V.
That's my answer and I'm stickin' to it.

Shouldn't that be 1880 uVF

Shouldn't that be 1880 uVF

Units of Hz is 1/sec. Units of R*C is sec. They cancel.

Ohms=volts/amp=volts/coulomb/second

Farads=coulombs/volt
Therefore,
Ohms*Farads=seconds

Which we all knew anyway (RC time constant).

Wow, looks like someone is dedicated to their homework.

How does anyone know how C1 and R1 are connected?

We don't. A nonsensical question spawns nonsensical answers.

Aww you've ruined our game.

You should have joined in. You never know when some fool will let the air out of the ball.
