EGR203 Electric and Electronic Circuits Assignment 4

  1. Determine the Thévenin voltage and resistance of the circuit below. Use the Thévenin equivalent circuit to determine the voltage across and current flowing through the load resistor.

    R1 (ohms)R2 (ohms)R3 (ohms) RL (ohms)Vs (volts)
    100400802406

  2. Find the load resistance for maximum power transfer in the circuit above.

  3. Replace the load resistance in the circuit above with a 3 Volt battery. Find the current flowing through the battery. Is the battery being charged (power absorbed) or discharged (power generated)?

  4. Find the Thévenin voltage and resistance for the circuit below.

  5. Find the voltage vc in the circuit below
