Question

find the equivalent resistance of 800 ohms, 4 kilo-ohms, and 1500 ohms in series and in parallel.​

Answer 1

Answer:

Series 6300 ohmn and parallel 460.83 ohms

Explanation:

Data :

  Resistance R1 = 800 ohms

 Resistance R2 = 4 kilo ohms = 4000 ohms

Resistance R3  = 1500 omhs

So formula for equalivent series resistance

    R = R1 + R2 + R3 = 800 + 4000 + 1500 = 6300ohms

For parallel equalivent resistance

     1/R = 1/R1 + 1/R2 + 1/R3 =  1/800 + 1/4000 + 1/1500 =

  1/R = 0.0021666666666

R = 460.82949308755 ohms
