equations

Question 1

Ohms law

Answer 1

V=IR

Question 2

What is boyles law

Answer 2

K=PV
as a volume of gas is decreased at a constant temp its pressure will increase

Question 3

What is Charles Law

Answer 3

At a constant pressure, the volume of gas varies with its absolute temperature
k = v/t

Question 4

What is guy-lussacs law

Answer 4

at a constant volume, the absolute pressure of a given mass of gas varies directly with the absolute temperature

Question 5

What is the equation for power (watts)

Answer 5

power (watts) = VI = I2R

Question 6

What is the equation for capacitance

Answer 6

C = q/v
q = charge (coulombs)

Question 7

What is the equation for charge

Answer 7

q = amperes (a) x seconds

Question 8

What is the equation for resistors in parallel

Answer 8

1/rt = 1/r1 +1/r2 etc

Question 9

What is the equation for resistors in series

Answer 9

Rt = r1 + R2 + R3 etc

Question 10

What is the equation for work done

Answer 10

work done = force x distance
unit of work = Nm

Question 11

What is the equation for stored energy (defibrillator)

Answer 11

Stored energy = 0.5CV2 = 0.5QV
