Question

Which of these best describes the current in a circuit consisting of one 12.0 V battery connected to a 6.00 Ohm resistor? 2.00 electrons flow through a point in the circuit every second 2.00 Coulombs of charge flow through a point in the circuit every second 2.00 Coulombs of charge flow through a point in the circuit every minute 2.00 electrons flow through a point in the circuit every minute none of these

Answer 1

2.00 Coulombs of charge flow through a point in the circuit every second

Explanation

Step 1

find the current in the circuit:

Current is just the rate of flow of electric charge. In simple words, the current is the rate at which electric charge flows in a circuit at a particular point

it can be calculated using the expression

$I=\frac{V}{R}$

where v is the voltage and R is the resitance

so

a) let

$\begin{gathered} V=12.0\text{ v} \\ R=6\Omega \end{gathered}$

now, replace

$\begin{gathered} I=\frac{V}{R} \\ I=\frac{12.0\text{ v}}{6.0\text{ }\Omega}=2\text{ Amperes} \\ I=2\text{ Amperes} \end{gathered}$

An ampere , is the international unit used for measuring current. It expresses the quantity of electrons flowing past a point in a circuit over a given time.

$1\text{ Ampere=}\frac{1\text{ C}}{1\text{ sec}}$

so, the answer is

2.00 Coulombs of charge flow through a point in the circuit every second
