In an electrical circuit, if resistance is doubled, EMF (measured in volts) stays constant, and current is halved.

What is the relationship among voltage circuit and resistance in a circuit?

Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)


What kind of force keeps current flowing in a circuit?

Electric potential difference or voltage is the force that keeps current flowing in a circuit. The potential difference creates an electric field, which in turn exerts a force on the charged particles in the circuit, causing them to move and establish a current flow.


How does changing the voltage in a circuit affect the current in the circuit?

Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.


What does the voltage current graph represent in an electrical circuit?

The voltage-current graph in an electrical circuit represents the relationship between voltage (V) and current (I) flowing through the circuit. It shows how the current changes with respect to the voltage, indicating the behavior and characteristics of the circuit components.


What controls the flow of electric current?

The flow of electric current is controlled by the voltage applied to a circuit. Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.


If voltage changes in a ac circuit what happens to current?

Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage. The answer is "yes",voltage remains the same as current moves through the circuit.As the voltage remains constant, current increases in the circuit.


What happened if the capacitor is in line when there is no load?

When there is no load on a circuit with a capacitor in the line, no current will pass. The capacitor, if charged, will remain charged until a load is put on to the circuit at which time it will discharge its designed output voltage.


Who invented the voltage current and resistant?

Newton


What are the 2 rules for the voltage and current in a series circuit?

In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.


If voltage is increased in a circuit what happens to current series and parallel respectively?

In this case current flows from a high voltage to a lower voltage in a circuit.


What is the derivative of current with respect to voltage in an electrical circuit?

The derivative of current with respect to voltage in an electrical circuit is called conductance, which represents how easily current flows through the circuit in response to changes in voltage.


What is the relationship between voltage potential and electrical current flow in a circuit?

Voltage potential is the force that pushes electrical current through a circuit. The higher the voltage, the greater the potential for current flow. In other words, voltage drives the flow of current in a circuit.
