A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage
<<>>
Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
What else can I help you with?
How do we usually think of voltage as the cause and currents the effect?
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
Why do signs say Danger High Voltage instead of Danger High current?
Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire). As high voltage is present in transmission lines, Danger-high voltage is written.
What is mean't by Reverse voltage?
Reverse voltage is voltage is applied in reverse. Instead of the positive voltage going into the anode lead of a component, it goes into the cathode lead of the component.
How does voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
How do we usually think of voltage as the cause and currents the effect?
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
What does voltage cause?
Voltage causes the flow of electric current in a circuit. It is the driving force that pushes electrons through a conductor, allowing electrical devices to operate. The higher the voltage, the more current will flow through the circuit.
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
Will the source voltage lead or lag the current in a circuit?
In an AC circuit, the source voltage can either lead or lag the current, depending on the type of load. Inductive loads cause the voltage to lag the current, while capacitive loads cause the voltage to lead the current.
How does a voltage cause current to do work?
When a voltage is applied across a circuit, it creates an electric field that exerts a force on the charged particles in the circuit, causing them to move and thus creating a current. This current flowing through a load, such as a light bulb or motor, can perform work by converting electrical energy into other forms, such as light or mechanical motion.
What forces cause current to move?
Voltage

What is the cause of voltage drop in electrical circuits?
Voltage drop in electrical circuits is caused by the resistance in the circuit components, such as wires, connections, and devices, which leads to a decrease in voltage as current flows through them.
What is applied to a conductor to cause current flow?
voltage is applied to a conductor to cause a current flow
What cause the voltage t lead current in an ac circuit?
Voltage leads current or, more specifically current lags voltage, in an inductive circuit. This is because an inductor resists a change in current.
