Question

Judge the equivalent resistance when the following are connected in parallel -a)1ohm and 10^6 ohm b) 1 ohm and 10^3 ohm and 10^6 ohm.​

Answer 1

Answer:

option (a)is the correct answer

Answer 2

Answer:

a) 1/1 + 1/10^6

= 10^6+1/10^6

=10^6/10^6+1

= 1000000/1000001 = 0.999999 ohm

b) 1/1 + 1/10^3 + 1/10^6

= 10^6 +10^3+ 1 /10^6

= 1001001/1000000

= 1.001001 ohm
