Convert the constant current source in Fig. 1.18 into equivalent voltage source

A generator develops 200 V and has an internal resistance of 100 Ω. Find the power delivered to a load of (i) 100 Ω (ii) 300 Ω. Comment on the result.

An audio amplifier produces an alternating output of 12 V before the connection to a load. The amplifier has an equivalent resistance of 15 Ω at the output. What resistance the load need to have to produce maximum power ? Also calculate the power output under this condition.

For the a.c. generator shown in Fig. 1.22 (i), find (i) the value of load so that maximum power is transferred to the load (ii) the value of maximum power.

Using Thevenin’s theorem, find the current through 100 Ω resistance connected across terminals A and B in the circuit of Fig. 1.27.

Show that when Thevenin’s equivalent circuit of a network is converted into Norton’s equivalent circuit, I_N = E₀ /R₀ and R_N = R₀. Here E₀ and R₀ are Thevenin voltage and Thevenin resistance respectively.
