Question

Determine the current drawn from a 12 V supply with internal resistance 0.5 Ω by the infinite network shown in Fig. 3.32. Each resistor has 1 Ω resistance.

Answer 1

The resistance of each resistor connected in the given circuit, R = 1 Ω Equivalent resistance of the given circuit = R’ The network is infinite. Hence, equivalent resistance is given by the relation,

Negative value of R’ cannot be accepted. Hence, equivalent resistance,
