Question

Hello I need help with this
if the power that a toy needs to work is 5 w and it does that with a 12 v battery how can I make that toy works with just a 6V battery.

Answer 1

Generally electronic toys are set to a specific voltage, in your case 12 V, at 5 W it would up a current of 5/12 A and a battery would not last long. I you redesign the toy for 6 V it would use 5/6 A and again it would not run long.

Answer 2

i know i need tiwce the current but how i achieve that without afecting the toy.i mean component have to add that is not another 6 v battery

Answer 3

or how can i modify the circuit

Answer 4

You generally will need a schematic of toy, then determine if components can be used at new voltages. I not sure what your really trying to do, most manufacturer decide the best and most inexpensive manner of development. If you really learn how the toy was designed then you might be able to design another with different components. The process is called reverse engineering, be careful you don't run into patent infringements.

Answer 5

first it is not a real toy, it´s just a homework. what it says is keep the power of the toy in 5w not using the 12 v battery the manufacturer says but a 6v battery. what i have done yet is represent the toy as a resistence(144/5ohm) and then add a new resistor called R, what i get is a negative value of R, so i google it and what it says is that there isn´t real negative resistor so the answer is. so the answer is what component in real life can i use to keep that power

Answer 6

You may be reading the question wrong. It might be a 6 V. 5 W toy and you want to use a 12 v battery. In this case the input current is 5/6 A and you want to reduce the 12 V battery to 6 V at the toy. You do this by dropping 6 V across a resistance with 5/6 A flowing through it, which would be 36/5 ohms. You must consider it's wattage which must be less than 5 W.

i check on that. thanks thought
