Five resistors are connected between points X and Y as shown in the diagram. A current of 10 A flows in the network from X to Y, then

Option: 1

the potential difference between X and Z is equal to that between Z and Y


Option: 2

the potential difference between X and Z is more than that between Z and Y


Option: 3

the potential difference between X and Z is less than that between Z and Y


Option: 4

the potential difference between Z and Y is 24 V

Total resistance

=\frac{6 \times 4}{6+4}+\frac{1}{\left(\frac{1}{4}+\frac{1}{8}+\frac{1}{6}\right)}=2.4+\frac{24}{13}=2.4+1.846

\mathrm{V}_{\mathrm{XZ}}=2.4 \times 10=24 \mathrm{~V}

\mathrm{V}_{\mathrm{ZZ}}=1.85 \times 10=18.5

\therefore \quad \mathrm{V}_{\mathrm{XZ}}>\mathrm{V}_{\mathrm{ZY}}
