A lamp has a current of 2.17 A. In hours, how long does it take for 1 mole of electrons to pass through the lamp?

Gennadij [26K]

Answer: The amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

Explanation:

We are given:

Moles of electron = 1 mole

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of particles.

We know that:

Charge on 1 electron = $1.6\times 10^{-19}C$

Charge on 1 mole of electrons = $1.6\times 10^{-19}\times 6.022\times 10^{23}=9.6352\times 10^4C$

To calculate the time required, we use the equation:

$I=\frac{q}{t}$

where,

I = current passed = 2.17 A

q = total charge = $9.6352\times 10^4C$

t = time required = ?

Putting values in above equation, we get:

$2.17A=\frac{9.6352\times 10^4C}{t}\\\\t=\frac{9.6352\times 10^4C}{2.17A}=44402s$

Converting this into hours, we use the conversion factor:

1 hr = 3600 seconds

So, $44402s\times \frac{1hr}{3600s}=12.33hr$

Hence, the amount of time needed for 1 mole of electrons to pass through the lamp is 12.33 hrs.

8. A thin slice of silicon that contains many solid-state components is a(n)

Sergio [31]

Question 8
Silicon is a semi-conductor that are mostly used in electronic devices. From the choices give, silicon is applicable in transistor, integrated circuit and diode. But the best answer that suits this question is (B) integrated circuit.

Question 9
Power is the rate of doing work. It is calculated as,

Power = workdone/time taken to do that work.

In electricity, power = current ×voltage
From ohm's law, V=IR
Where I⇒current and
R⇒ resistance.

∴Power = I²R
= 6²×5
= 180 Watts
