A toy car has a 1.5-A current, and its resistance is 2 . How much voltage does the car require?

Respuesta :

AL2006

Voltage = (current) x (resistance)

Voltage = (1.5 A) x (2 ohms)

In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE 3 volts from the battery.

Answer: The correct answer is 3 V.

Explanation:

The mathematical expression form Ohm's law is as follows;

V=IR

Here,  V is the potential, R is the resistance and I is the current.

It is given in the problem that a toy car has a 1.5-A current, and its resistance is 2 .

Put I= 1.5 A and R= 2 ohm in the above expression.

V=(1.5)(2)

V=3 V

Therefore, the voltage required by the car is 3 V.
