In a lightning discharge, 45 C of charge move through a potential difference of 1.0 x108 V in 0.030 s.A. What is the current of the lightning strike?B. How much energy is released by the lightning bolt?

Respuesta :

Given:

Charge, Q = 45 C

Potential difference, V = 1.0 x 10⁸ V

Time, t = 0.030 s

Let's solve for the following:

• (A). What is the current of the lightning strike?

To find the current, apply the formula:

[tex]I=\frac{Q}{t}[/tex]

Where:

I si the current

Q is the charge = 45 C

t is the time = 0.030 s

Thus, we have:

[tex]\begin{gathered} I=\frac{45}{0.030} \\ \\ I=1500\text{ A} \end{gathered}[/tex]

Therefore, the current of the lightning strike is 1500 Amperes.

• (B). How much energy is released by the lightning bolt?

To find the amount of energy released, apply the formula:

[tex]E=V\times Q[/tex]

where:

E is the Energy released

V is the potential difference, V = 1.0 x 10⁸ V

Q is the charge = 45 C

Thus, we have:

[tex]\begin{gathered} E=1.0\times10^8\ast45 \\ \\ E=4.5\times10^9\text{ J} \end{gathered}[/tex]

Therefore, the energy released is 4.5 x 10⁹ Joules.

ANSWER:

(a). 1500 A

(b). 4.5 x 10 J
