Question

Find the equivalent resistance when two resistors of resistance 1 ohm and 
1000000 ohm are connected in parallel.

please answer, please.
​

Answer 1

Explanation:

In series combination,

R+R = Rs

1+1 = 2 ohm

In parallel combination,

1/R + 1/R = 1/Rp

1/1000000 + 1/1000000 = 1/500000 ohm

Rp = 500000 Ohm

Now,

Equivalent resistance = Rs + Rp

= 2 + 50000

= 50002
