What happens to voltage and current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

What controls voltage and current?

Voltage mode and current mode are the two regulating conditions that control the output of the supply. Most applications call for a supply to be used as a voltage source. When the supply runs in current mode, the supply provides a constant current into a variety of load voltage conditions including a short circuit.

Is voltage or current more important?

An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.

What is the most common misconception about batteries?

The misconception tends to be implicitly rather than explicitly stated but the essential misunderstanding is that batteries want to produce a particular current. In other words there is this current that wants to flow and circuits try and resist or split this current. In other words people see batteries as constant current providers.

Are there any misconceptions about charge flow and batteries?

In many instances, these preconceived notions about charge flow and batteries are incorrect ideas and are completely inconsistent with the model presented here. Like all misconceptions in physics, they must be directly confronted in order to successfully build an accurate mental model of the physical world.

Why do we need to confront misconceptions in physics?

Like all misconceptions in physics, they must be directly confronted in order to successfully build an accurate mental model of the physical world. What Do You Believe?

What happens when voltage is removed from an electric circuit?

In electric circuits, resistance is always high, so voltage causes charge-flows. And, if we remove the voltage, the charge-flow drops to zero. But if this is true, then where did the voltage come from?
