What happens to current when voltage is increased ?
When voltage is increased in an electrical circuit, according to Ohm’s Law (V = IR), if the resistance (R) remains constant, the current (I) will increase proportionally. This means that as the voltage across a circuit or component increases, assuming the resistance stays the same, the current flowing through the circuit will also increase. This relationship is fundamental to understanding how voltage affects current in electrical systems.
Increasing voltage typically leads to an increase in current flow through a circuit, provided the resistance in the circuit remains constant. This is because higher voltage provides more “push” or potential difference for electrons to move through the circuit. As a result, electrons move with greater force and speed, causing an increase in the rate of flow of electric charge, which we measure as electric current.
Voltage drop occurs in a circuit when there is resistance to the flow of current. According to Ohm’s Law, V = IR, where V is voltage, I is current, and R is resistance, an increase in current (I) leads to an increase in voltage drop (V) across the resistive elements in the circuit. This occurs because the energy supplied by the voltage is dissipated as heat and other forms of energy as current flows through resistive elements.
When applied voltage is increased in a circuit, assuming the resistance remains constant, the current flowing through the circuit will also increase. This relationship is governed by Ohm’s Law, which states that the current (I) in a circuit is directly proportional to the applied voltage (V) and inversely proportional to the resistance (R). Therefore, a higher applied voltage results in a higher current flow through the circuit, assuming the resistance remains unchanged.
When the voltage across a circuit or component increases, according to Ohm’s Law (V = IR), if the resistance (R) remains constant, the current (I) will increase proportionally. This means that as the voltage increases, assuming resistance stays the same, the current flowing through the circuit will also increase. This relationship illustrates how voltage and current are directly related in electrical circuits, with an increase in voltage resulting in a corresponding increase in current flow, given a constant resistance.
