Hi everyone, I'm stuck on a homework problem for my Electronics 101 course. My teacher has not responded to any emails and has canceled office hours 5 weeks as well as 4 classes this semester so I haven't had any luck getting help from him. Anyway, this is the question.
Given the circuit below, what is the value of R1?
Because I cant figure out how to copy a photo over, I will describe the circuit to the best of my ability.
Parallel with 3 resistors.
R1 = ?
R2 = 5.1kOhms
R3 = 10kOhms
Vs = 24.0V
10mA
This is the furthest I have gotten so far (with minor variations through trial and error)
I attempted to solve for I2 & I3 through Ohms Law for their individual values (I2=V/R2) & (I3=V/R3) which resulted in 4.7ma & 2.4ma
Then, I subtracted these two values from It (10ma) which gave me 2.9 as I1
I used R=V/I to solve for its resistor value R=24V/2.9mA (0.0029A)
Which gave me 8,275.86 which was incorrect.
Please advise. Thank you for your time.
