Chapter 7
Current
I= q/t
I= P/V
I= V/R
Electric field strength
Electric field strength= force on a charged object/charge on the object
Voltage
V=work(energy)/q
Electrical force between two objects
F=9X10^9
(q1
q2/d^2)
Power
P= E/t
Chapter 8
Vo/Vi=No/Ni
λmax=0.0029/T
P input=P output
Chapter 6
Speed
Speed of sound
v= 20.1 *√T
Speed of the wave
v= f * λ
Speed of wave on the string
v = √ F/𝜌
Linear Mass
𝜌=m/l
