# Task 4.3 - Determine electrical parameters in series and parallel electrical networks

A) A battery with a terminal voltage of 9 V is connected to a circuit consisting of four 2002 and one 100 resistors all in series. Assume the battery has negligible internal resistance.

a) Calculate the equivalent resistance of the circuit.

b) Calculate the current through each resistor.

c) Calculate the potential drop across each resistor.

d) Determine the total power dissipated by the resistors and the power supplied by the battery.

B) Three resistors R₁=1.000, R₂=2.000, and R3-2.000, are connected in parallel. The parallel connection is attached to a v=3.00v voltage source.

a) What is the equivalent resistance?

b) Find the current supplied by the source to the parallel circuit.

c) Calculate the currents in each resistor and show that these add together to equal the current output of the source.

d) Calculate the power dissipated by each resistor.

e) Find the power output of the source and show that it equals the total power dissipated by the resistors.
