There is a single path for electrons.

the current decreases when additional resistors are added.

the current will be the same in each resistor.

these statements best describe a(n) circuit.

a) closed

b) open

c) parallel

d) series

D. series

Explanation:

If  a series circuit has multiple resistances and , and has voltage source , then the current is given by

From this equation we see that as we add more and more resistors to the circuit, more terms are added in the denominator, which results in a decreased current .

In a series circuit there is only one path for the electrons to flow, and by the principle of the continuity of current, the current must be same throughout the path—the current cannot jam just as flowing water  cannot collect in the pipe—what goes in has to come out.

This means the current cannot jam in the resistors, and therefore it must be the same in every resistor no matter how many resistors you add.

i believe it is b. what was the cause of the big bang

hope this !

heat the gas and measure the pressure
