I'm extending my question from previously.
I'm doing some calculation and find something confusing below is the calculations:
V = 5
R = 1000
I = V/R = 5/1000 = 0.005A
P = IxV = 0.005A x 5V = 0.025W = 1/40W
1/40W is output for me to find the right size of SMD now confusion kicks in when I change the values see below
now let's change this to
V = 5
R = 10000 (10k)
I = V/R = 5/10000 = 0.0005A
P = IxV = 0.0005A x 5V = 0.0025W = 1/400W << that's 400 m'i doing something wrong from the SMD power rating chart i cant any bigger than 1/20 ? how to resolve this?
Now let's come to my real problem see below.
V = 3.3
R = 0.10 ohms
I = V/R = 3.3/0.10 = 33A << ??
P = IxV = 33A x 3.3V = 108.9W = 108 9/10 << ??
See the Circuit and focus on R2 and R3 value. Can someone help to understand me this? or correct me what I'm doing wrong? There is no way its 33 Amps of current for this what will be the correct power rating for this R2 and R3 based on the inputs mentioned on the circuit, V = 3.3 and R2, R3 = 0.10 ohms
if anyone can show me the calculation for the above problems and advise me the correct way of calculation, I have created an excel sheet to make life easy but unable to figure it out whats is wrong when changing the value and if any of you can help me to improve that sheet for the public I'll appreciate
