Ohm's law helps us in determining either voltage, current or impedance or resistance of a linear electric circuit when the other two quantities are known to us Ohm’s law describes the relationship between three quantities: voltage across a resistor, current through the resistor, and the resistance of the resistor — but Ohm’s Law does not give any description about the “causal relationship” between those three
Appliances such as electric heaters, electric ovens, and toasters all use resistors to turn current into heat, then using the heat lost from this resistor to warm the surrounding area. ... Resistors also have applications in electrical devices like computers and cell phones to damp out unwanted electrical signals because Electric current are the charges that flow,
Voltage is the source of enery that keep and pushes the charges to flow while
Resistance stop /limit the flow
