Pulse Height Of Pulse Amplifier
 
1 Attachment(s)
1. The problem statement, all variables and given/known data

I have attached the question as a photo. It contains two parts.

2. Relevant equations



3. The attempt at a solution

For part A, is it simply Q=CV where C is given and Q is the elementary charge times 10^6?


For B, I am not quite sure where to begin.

Any advice on both parts is appreciated. Thank you very much, in advance.

Use Ohm's law to find the current, I.

I = ΔQ / Δt.

Find how much charge passes any point in the circuit in 1 microsecond.

Thanks for responding. Is my thinking for part A correct?

And for part B, I get a value of .05 A but how do I convert that to the needed result? Is .05 A in terms of seconds, and I have to divide by 10^-6?

What is the definition of an ampere?

Coulomb per second I believe. So would it just be that number over 10^-6?

Coulombs per second times 10‒6 seconds gives Coulombs.

Ahh ok that's what I meant. Thanks. Are the rest of my thoughts correct?
