Can I use 5V to a 3V device
It could result in immediate failure that could result in smoke or even fire.
How to amplify 3V to 5V
The main ways to interface a 3.3V output to a 5V input are:Direct connection.Using a 74HCTxx gate (or other 5-V TTL-input compatible families)Using a diode offset.Resistor Offset.BJT/MOSFET inverter.Series MOSFET.Series BJT.Level Translator IC.
How to reduce 5V to 3V
The output voltage of the circuit is the same as the voltage applied to the input. To convert the 5V signal to a lower 3V signal, we just add a resistive attenuator. If the resistor divider precedes the unity gain follower, it will provide the lowest impedance for the 3.3V circuit.
Can I use 5V charger for 3V
Can I use A 5V adapter to power A 3V device It could result in immediate failure that could result in smoke or even fire.
Can I use 5V charger for 3V battery
Probably not directly. A 5V charger has a specified voltage. If 5V are applied to a discharged Lithium-Polymer battery (around 3V), the current going into the battery might be several times over the maxium tolerable charging current for a 380mAh battery, which would be 380mA (better is 100mA).
Will 5V work with 3.3 V
A 3.3 V device can interface with a 5V device without any additional components. For example, a logic 1 (HIGH) from a 3.3 V device will be at least 2.4 V. This will still be interpreted as a logic 1 (HIGH) to a 5V system because it is above the VIH of 2 V.
Can 3V LED run on 5V
You need to have that order of "leeway" voltage across the resistor in order to allow for variations in the LED voltage, so for an LED with a conduction voltage of 3 V, it is generally not practical to operate it from less than 5 V.

What would happen if A 3V appliance used A 5V battery
The electrical appliance may get warm or overheat as 5V is more than required for it to work. The bulb will not light. The bulb will be dimmer than normal.
Can 5V charge 3.7 V
Charging a 3.7v battery with a 5v charger. Here's everything about using a 5 V charger to charge a 3.7 V cell phone battery being safe to use: It's not safe to charge a 3.7 V cell phone battery with a 5 V charger for both the equipment and personal safety.
