Question 73

A student connects various resistors in parallel pairs.

Which statement is correct?

A

A parallel pair of 6 Ω6\ \Omega6 Ω and 6 Ω6\ \Omega6 Ω. Statement: "The total resistance is 12 Ω12\ \Omega12 Ω."

B

A parallel pair of 12 Ω12\ \Omega12 Ω and 4 Ω4\ \Omega4 Ω. Statement: "The total resistance is more than 12 Ω12\ \Omega12 Ω."

C

A parallel pair of 8 Ω8\ \Omega8 Ω and 2 Ω2\ \Omega2 Ω. Statement: "The total resistance is between 2 Ω2\ \Omega2 Ω and 8 Ω8\ \Omega8 Ω."

D

A parallel pair of 15 Ω15\ \Omega15 Ω and 10 Ω10\ \Omega10 Ω. Statement: "The total resistance is less than 10 Ω10\ \Omega10 Ω."
