Question

Determine the current through each resister in the circuit diagram shown (see pic)

I at 100 ohms ---- ?

I at 200 ohms ---- ?

I at 250 ohms ---- ?

I at 350 ohms ---- ?

Answer 1

Here is the answer

R1 and R2 are prallel with equivalent resistance =71.42 ohm

R3 and R4 are prallel with equivalent resistance =127.27 ohm

Total Req=198.69 ohm

current=24/198.69=0.120 A

Current through R1=0.120*(250/350)=0.086 A

Current through R2=0.120*(100/350)=0.034 A

Current through R3=0.120*(200/550)=0.0436 A

Current through R4=0.120*(250/350)=0.076 A

Generally current through a parallel branch=I total*opposite resistance branch/total resistance

Answer 2

I1=V/R1=24/100 =0.24 amps

I2=v/R2=24/200 =0.12 amps

I3=v/R3=24/250 =0.096 amps
  
I4=v/R4=24/350 =0.0685 amps
