Which statement most accurately describes how a light bulb is affected by a switch in a circuilt that consists of a single loop?
a. the light bulb will be on regardless of the state of the switch
b. the light bulb will be off regardless of the state of the switch
c. the light bulb will be on if the switch is open
d. the light bulb will be off if the switch is open

The light bulb will be off if the switch is open,

Step-by-step explanation:

We know that the electric current cannot flow through an open circuit.

Therefore when the switch will be off, then the circuit is open and thus current cannot flow through it. Moreover each circuit has wires connected to each of the two terminals of the battery along with a light bulb.

Hence, the D is the correct option. " The light bulb will be off if the switch is open".

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
