Q3.
(a) Assume that the current flowing through a 1 kΩ resistor is
30 mA. If the current is to be reduced by 40%, what is the value of
a resistor that must be connected in series to the 1 kΩ resistor?

(b) Calculate the percentage drop of the power dissipated in the
circuit. (2 marks)
(c) Four 12 V voltage sources are connected in series. What is
the total voltage of the combination? (1 mark
