Voltage is the measure of electric potential difference between two points in a circuit, while current is the flow of electric charge through a circuit. In other words, voltage is the force that drives current.
Controlling voltage allows us to regulate the flow of electricity and prevent damage to electrical components. It also allows us to power different devices with varying voltage requirements.
Voltage can be controlled through the use of resistors, transformers, and voltage regulators. These components can increase or decrease the voltage in a circuit.
If the voltage in a circuit is too high, it can cause damage to electrical components and potentially start a fire. It is important to use voltage regulators and other control measures to prevent this from happening.
Yes, voltage can be controlled in both AC (alternating current) and DC (direct current) circuits. However, different methods may be used depending on the type of circuit.
