Question

Eight identical resistors ($r=\frac{15}{2}\Omega$) are connected along edge of a pyramid having square base ABCD as shown in figure. Then equivalent resistance between A and D in $\Omega$ is (Write upto two digits after the decimal point.)

Answer 1

Req = $\frac{8}{15}r=\frac{8}{15}\times \frac{15}{2}=4\Omega$
