Will a toy car travel faster if a battery with higher power is used?

help %26gt;.%26lt; i'm doing a project about battery powered toy cars. so will the battery power affect its speed?|||Yeah man absolutely|||Power is the product of current and voltage (P = IV).





The motor has a fixed resistance. The current drawn (I)is calculated by V=IR. Rearrange that to get I = V/R.





If you increase the voltage, you increase the current drawn. The resistance is fixed.





Increasing the current increased the power consumed (P=IV).





If by "increasing the power of the battery" you mean using a battery with a higher voltage, you will get more power in the motor. A higher-powered battery could be one that puts out the same voltage but can sustain it for longer before running out of juice. That won't get more power out of your motor (V is constant), but it will run for longer.|||Power = voltage * current


Voltage = current * resistance





I think you mean to use a battery with higher voltage. If you increase the voltage, keeping the resistance (the car's motor) the same, then the current will increase. (Increasing both the voltage and current, then the power will also increase.)





Increased current will turn the motor faster, so speed will increase, unless you burn out the car's motor and then speed will come to a halt.





So, be careful and don't increase the voltage too much.





NOTE: If increasing the voltage also increases the weight of the battery, then the resistance of the car will also increase and you might not get much of a speed gain. Reducing the weight of the car will help to reduce the resistance of the car which will increase current and therefore speed.
