Question

you have two resistors 10 ohm and 20 ohm what resistance can you get by combining the two​

Answer 1

Answer:

Heya Mate

Step-by-step explanation:

If we combine the 2 resistors in series

i.e. Rp=R1+R2

f

the equivalent resistance will be

10ohms+20ohms=30ohms

And applying parallel resistance

i.e

1/Rp=1/R1+1/R2

1/10+1/20=3/20

i.e.20/3ohms

=6.67 ohms[approx]

pls mark as brainliest^_^

Answer 2

Answer: 30 ohm in series and 20/ 3 ohm in parallel

Step-by-step explanation: Let R1 = 10 ohm and R2 = 20 ohm R eq ( in series)= R1 +R2

= 10 + 20

= 30 ohm

R eq( in parallel ) =1÷( 1/R1 + 1/R2)

=1÷( 1/ 10 + 1/ 20)

= 20/ 3 ohm

= 6.67 ohm ( approx)
