# What is current draw at idle?

## What is current draw at idle?

“Current draw” is the amount of AC current an amplifier demands while it is operating. Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full power, and full power, with all channels driven simultaneously.

Why does current go down when voltage goes up?

Higher resistance at a given voltage results in less current. V = IR, Voltage is constant, resistance is constant, therefore current (I) has to go down to satisfy ohm’s law. Therefore, stepping up voltage results in a proportional step down in current.

What does idle current mean?

When used precisely, “idling current” refers to the current needed to keep an electronic circuit (or a single device such as a vacuum tube or bipolar junction transistor) biased in its chosen operating condition in the absence of an input signal.

### What is draw current?

Used almost exclusively in the term “Drawing Current” “Current” is a term we use to visualize/represent/measure electricity running through a wire. When people say a device is “drawing current” they simply mean that the device is pulling or using power from the power supply.

Does less resistance mean more voltage?

This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease.

Does low resistance Mean High voltage?

If the resistor is in series with some other element, and they together are powered by a constant voltage source, then the voltage dropped across the resistor means there’s less voltage available for the other circuit element. It doesn’t mean that the voltage of the source decreased. That’s not Ohm’s law.

## What is low voltage and high current?

Definition

IEC voltage range AC RMS voltage (V) Defining risk
High voltage > 1 000 Electrical arcing
Low voltage 50 to 1 000 Electrical shock
Extra-low voltage < 50 Low risk

What happens to voltage if current increases?

Originally Answered: When current increases, what happens to voltage? If current increases in a conductor there will be increased voltage drop in electrical conductors so there will be less voltage at the load. That is one reason why we use larger cables for higher current flow, to reduce voltage loss in the conductor.
