Question

1.6*10 to the power of -19 C charge flows through a conductor in 10 to the power of -10 seconds.find
the current flowing through the
conductor

​

Answer 1

Answer: 1.6x10^-9C

Explanation:

t =10^-10s

Q=1.6 x10^-19 c

I=?

I = Q/t

= 1.6x10^-19c/10^-10s

=1.6x10^-19x10^10

=1.6x10^-9 A

Answer 2

The current flowing through the conductor is equal to 1.6 nano-ampere.

Given:

The amount of charge flown (Q) = 1.6 × 10⁻¹⁹ C

The total time taken (T) = 10⁻¹⁰ seconds

To Find:

The current flowing through the conductor.

Solution:

→ The current is defined as the rate of flow of charge. The current flowing through a conductor is equal to the amount of charge flowing through the conductor per unit of time.

→ To calculate the current flowing, we divide the total charge flowing (Q) by the total time taken (T).

→ In the given question, the amount of charge flowing (Q) through the conductor is equal to 1.6 × 10⁻¹⁹ C and the total time taken (T) is equal to 10⁻¹⁰ seconds.

Let the current flowing through the conductor be 'i'.

                         $\therefore\:Current(i)=\frac{Amount\:of\:charge\:flown(Q)}{Total\:time\:taken(T)}$

                                         $\\\\\therefore\:i=\frac{Q}{T} \\\\\therefore\:i=\frac{(1.6\times10^{-19}) }{(10^{-10}) } \\\\\therefore\:i=1.6\times10^{-9} \:Ampere\\\\\therefore\:i=1.6 \:nA$

Therefore the amount of current flowing through the conductor is equal to 1.6 nano-ampere.
