## Which comes first voltage or current?

Originally Answered: Who comes first voltage or current ? Current flows AFTER the two points having potential difference (voltage) are connected. Hence voltage comes first.

### What is relationship between current and voltage?

Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.

#### What kills a person voltage or current?

Current will kill you but some amount of voltage is required to flow that current in the body breaking the human body resistance. In other words, an enough power is required to pass in the human body for proper electric shock.

Is voltage proportional to current?

Current is directly proportional to the voltage. A fourfold increase in the voltage would cause a fourfold increase in the current.

Why is current low when voltage is high?

High voltage transmission minimizes the amount of power lost as electricity flows from one location to the next. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.

## Is voltage proportional to current in AC?

In AC the Current is only directly proportional to the voltage in a pure resistive load. Whenever there is a reactive (Inductive or Capacitive) load, the current will be out of phase by an amount determined by the reactance value.

### Why current is not directly proportional to voltage?

Current flow is the result of application of Voltage across the two terminals of a closed circuit. Hence, we say that the amount of current flow in a circuit is directly proportional to the applied voltage and not the other way round. because current depends on voltage. voltage does not depend on current.

#### Does higher voltage mean higher current?

The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. The lower current that accompanies high voltage transmission reduces resistance in the conductors as electricity flows along the cables.

Can voltage exist without current?

It is possible to have voltage without current, but current cannot flow without voltage.

What is the highest voltage possible?

one million volts

## What happened to the current in short circuit?

When a short circuit occurs, electrical current experiences little or no resistance because its path has been diverted from its normal direction of flow. This in turn produces excess heat and can damage or destroy an electric appliance.

### Why does current increase in short circuit?

Short circuit occurs when resistance of that device i.e. internal resistance and resistance that we apply to the circuit i.e. external resistance cannot resist it since R=0. At the time of short circuit, large amounts of current flow means current increases and large amounts of energy is delivered through the circuit.
