Question 639: Current Electricity

Question

The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is 0.25$$\Omega$$. What will be the effective resistance if they are connected in series?

Accepted Answer

$${R \over 4}$$ = .25
R = 1
Now these four resistances are arranged in series
R
S
= R + R + R + R = 4R
= 4 $$ 	imes $$ 1 = 4$$\Omega$$

Answer

4$$\Omega$$

Answer

0.25$$\Omega$$

Answer

0.5$$\Omega$$

Answer

1$$\Omega$$
