## Q3

still working on #2 but here's #3

Imax=2*pi*f*C*Vmax, then plug in converting C *10^-6

so C=19.73

Vmax=70.5

Imax=.2608

.2608=2*pi*f*(19.73*10^-6)*70.5

f=29.84

answer is negative

## Q1+4

while im here might as well put these up too

1)

Irms=(Imax/sqrt(2))

given Irms, solve for Imax

answer is negative

4)

first find Vmax by

Vrms=(Vm/sqrt(2))

then

Vmax=2*pi*f*L*Imax

solve for Imax, its a straight plug in problem L is in Henrys

answer is positive

## #2

voltage given/square root of 2 = V_rms

(V_rms/resistance given)*V_rms = answer

answer is positive

(V_rms/resistance given)*V_rms = answer

answer is positive

## question2

Hey i am confused about the equation given.

voltage given/square root of 2 = V_rms

(V_rms/resistance given)*V_rms = answer

the second equation why do you have to divide and multiply by V_rms? Is there an error in this equation because it isnt working for me.
