Question

(a) In a series circuit, the total resistance is always _____ than any resistor in the circuit.

(b) According to the voltage divider rule, for a series circuit containing 100 Ohm, 9 K Ohm, and 5 K Ohm resistors and a voltage source, the largest voltage drop is expected to be across which resistor?

(c) Three resistors R1, R2 and R3 are connected in series with a 20V source, if R1 is 5 ohms and 1.5 A of current is flowing through it, what is the current through R3?

(d) State Kirchhoff's voltage law.

(e) The voltage regulation of generator A is 7% and that of generator B Which is 3%. Which is a better generator?

Answer 1

for answer c :- if the resistors are in series then the current passing through every resistor is same that is 1.5 through R3
