Answer:

2.38Ω

Explanation:

We are given;

  • Voltage as 5.0 V
  • Current as 2.1 A

We are required to calculate the resistance of the iPhone battery;

  • According to Ohm's law, the current through a conductor is directly proportional to the potential difference at constant temperature and pressure.
  • That is; V = IR
  • Rearranging the formula;

R = V/I

Therefore;

R = 5.0 V ÷ 2.1 A

  = 2.38 Ω

Thus, the resistance of the iPhone battery is 2.38Ω
