Final answer:

To determine the resistance of a toy car with a 3-V battery and a current of 0.15A, we use Ohm's Law (R=V/I), which yields a resistance of 20 ohms.

Step-by-step explanation:

To find the resistance of a toy car connected to a 3-V battery with a current of 0.15A flowing through it, we can use Ohm's Law, which states that the voltage (V) across a resistor is the product of the current (I) flowing through it and the resistance (R) of the resistor.

The equation is V = IR.

In order to calculate the resistance of the toy car, we rearrange the formula to solve for resistance, giving us R = V/I. Here, we have a voltage (V) of 3 volts and a current (I) of 0.15 amperes.

By substituting the given values into the equation, we get R = 3V / 0.15A.

Performing the calculation, we get:

R = 3V / 0.15A

= 20 ohms

Therefore, the resistance of the toy car is 20 ohms.
