Calculations

Question 1

What is the formula for calculating peak voltage?

Answer 1

Peak voltage = Peak-to-peak voltage / 2

Question 2

What is the formula for calculating RMS voltage?

Answer 2

RMS = Peak voltage x .707

Question 3

What is the formula for calculating current when you know RMS and R?

Answer 3

I = RMS / R

Question 4

What is the formula for calculating PEP when you know RMS and I?

Answer 4

PEP = RMS * I

Question 5

How do you calculate the number of PEP watts dissipated when you know I and R

Answer 5

V (RMS) = I * R

PEP = V * I

Question 6

How do you calculate RMS voltage when you know resistance and power?

Answer 6

V (RMS) = sqrt(P x R)

Question 7

How do you calculate PEV (peak envelope voltage)?

Answer 7

Peak voltage = Peak-to-peak voltage / 2

RMS = Peak voltage x .707

PEV = RMS x 1.414

Question 8

How do you calculate RMS voltage when you know the PEV (peak envelope voltage)?

Answer 8

RMS = PEV x .707

or

RMS voltage = Peak voltage x 0.707
