Question

Consider a 450-ohm resistor and a 310-ohm resistor.

a) What is their equivalent resistance in ohms if they are connected in series?

b) What is their equivalent resistance in ohms if they are connected in parallel?

c) What is the equivalent resistance in ohms if we connect a pair of 310 -ohm resistors in series?

d) What is the equivalent resistance in ohms if we connect a pair of 310 -ohm resistors in parallel?

d) What is the equivalent resistance in ohms if we connect four of 310 -ohm resistors in parallel?

Explanation / Answer

Consider a 450-ohm resistor and a 310-ohm resistor.

a) What is their equivalent resistance in ohms if they are connected in series?

450+310 = 760

b) What is their equivalent resistance in ohms if they are connected in parallel?

450*310 / (450+310) = 183.55

c) What is the equivalent resistance in ohms if we connect a pair of 310 -ohm resistors in series?

620

d) What is the equivalent resistance in ohms if we connect a pair of 310 -ohm resistors in parallel?

155

d) What is the equivalent resistance in ohms if we connect four of 310 -ohm resistors in parallel?

77.5
