Peter connects a 13 V battery across a wire for a period of time. During this time, the battery transfers 6 x 10⁴ J of energy. How much charge flows through the wire? Give your answer to 0 decimal places.

Answer :

To solve this problem, we need to understand the relationship between voltage, energy, and charge.

In physics, the relationship is given by the formula:

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

where:

  • [tex]E[/tex] is the energy transferred in joules (J),
  • [tex]V[/tex] is the voltage in volts (V),
  • [tex]Q[/tex] is the charge in coulombs (C).

We are given:

  • Voltage [tex]V = 13[/tex] V,
  • Energy transferred [tex]E = 6 \times 10^4[/tex] J.

We need to find the charge [tex]Q[/tex]. We can rearrange the formula to solve for [tex]Q[/tex]:

[tex]Q = \frac{E}{V}[/tex]

Substitute the given values into the formula:

[tex]Q = \frac{6 \times 10^4}{13}[/tex]

Calculating this, we have:

[tex]Q \approx 4615.384615[/tex]

Rounded to 0 decimal places, the charge [tex]Q[/tex] is approximately 4615 C.

Therefore, the amount of charge that flows through the wire is 4615 coulombs.
