You short-circuit a 9 volt battery by connecting a short wire from one end of the battery to the other end. If the current in th

e short circuit is measured to be 16 amperes, what is the internal resistance of the battery?

Answer:

The internal resistance of the battery is 0.562 ohms.

Explanation:

Given that,

Voltage of battery, V = 9 volts

Current in the short circuit, I = 16 A

  • In case of short circuit, the external resistance of the circuit will be equal to 0.

So, we can say that, the internal resistance of the battery is given by :

r=\dfrac{V}{I}\\\\r=\dfrac{9}{16}\\\\r=0.562\ \Omega

So, the internal resistance of the battery is 0.562 ohms.

Neporo4naja [7]
A motion security line is a system that is used to detect motion.
The input for the system is MOTION and the output is LIGHT. That is, when the system detects motion it switch on light.
Remember, an Input is the information that was inserted into a system while the output is the result of the processed information.

Suppose a rectangular piece of aluminum has a length D, and its square cross section has the dimensions W XW, where D (W x W) to
Ludmilka [50]

Answer:

R₂ / R₁ = D / L

Explanation:

The resistance of a metal is

        R = ρ L / A

Where ρ is the resistivity of aluminum, L is the length of the resistance and A its cross section

We apply this formal to both configurations

Small face measurements (W W)

The length is

         L = W

Area  

         A = W W = W²

        R₁ = ρ W / W² = ρ / W

Large face measurements (D L)

       Length L = D= 2W

       Area     A = W L

     R₂ = ρ D / WL = ρ 2W / W L = 2 ρ/L

The relationship is

    R₂ / R₁ = 2W²/L
