If you wish to take a picture of a bullet traveling at 500 m/s, then a very brief flash of light produced by an rc discharge through a flash tube can limit blurring. assuming 1.00 mm of motion during one rc constant is acceptable, and given that the flash is driven by a 503 µf capacitor, what is the resistance in the flash tube?

Resistance in the flash tube,

Explanation:

It is given that,

Speed of the bullet, v = 500 m/s

Distance between one RC constant, d = 1 mm = 0.001 m

Capacitance,

The time constant of RC circuit is given by :

R is the resistance in the flash tube

..........(1)

Speed of the bullet is given by total distance divided by total time taken as :

Equation (1) becomes :

So, the resistance in the flash tube is . Hence, this is the required solution.

Explanation:

We are given that

Speed of bullet=500 m/s

Distance during one  RC time constant=d=1 mm=

Capacitance=

We have to find the resistance in the flash tube.

Hence, the resistance in the flash tube=
