Answer:
Explanation:
Let the resistance is R1 and R2.
Case 1: When they are connected in series.
Let the equivalent resistance is R.
V = 20 V
i = 2 A
R = V / i = 20 / 2 = 10 ohm
R1 + R2 = 10 ohm ...... (1)
Case 2: When they are connected in parallel.
V = 20 V
i = 10 A
R = 20/10 = 2 ohm
.... (2)
From equation (1) and equation (2), we get
R1 x R2 = 20
Put in equation (1), we get


Take positive sign
R1 = 7.24 ohm
So, R2 = 10 - 7.24 = 2.76 ohm
So, the greater value of resistance is 7.24 ohm.
