(a) R1 = 500 ohm, R2 = 1000 ohm
As per given figure,
R = R1 + R2
= 500 + 1000
= 1500 Ohm
(b) R1 = 2 ohm, R2 = 2ohm
As per given figure,
1/R = 1/R1 + 1/R2
1/R = 1/2 + 1/2
R = 1 ohm
(c) R1 = 4 ohm, R2 = 4 ohm, R3 = 3 ohm
As per given figure,
1/R = 1/R1 + 1/R2
1/R = 1/4 + 1/4
R = 2 ohm
Total resistance = R + R3
= 2 + 3 = 5 ohm
