A toy car has a 1.5-A current, and its internal resistance is 2 ohms.  How much voltage does the car require?
.75 J
3 J
.75 V
3 V

Respuesta :

Pretty sure it's 3v
But not 100%

Answer: Option (d) is the correct answer.

Explanation:

According to ohm's law, the current passing through a conductor is proportional to the voltage over the resistance.

Mathematically,      [tex]I = \frac{V}{R}[/tex]

where,         I = current

                   V = voltage

                   R = resistance

It is given that toy car has current (I) of 1.5 ampere and internal resistance or resistance of 2 ohms.

Therefore, calculate the voltage of the car as follows.

                   [tex]I = \frac{V}{R}[/tex]

                         V = I × R

                            = (1.5 ampere) × (2 ohms)

                            = 3.0 ampere ohms

                            = 3 volts

Thus, we can conclude that 3 volts of voltage is required by the toy car.
