How do we usually think of voltage as the cause and current as the effect?

Voltage is the Cause, Current is the Effect Voltage attempts to make a current flow, and current will flow if the circuit is complete. Voltage is sometimes described as the ‘push’ or ‘force’ of the electricity, it isn’t really a force but this may help you to imagine what is happening.

Does current follow voltage?

Voltage causes current through a closed circuit, but through an inductor it is the change in current that causes a voltage. Obviously there is no current without voltage. In a simple DC circuit there’s no doubt that voltage causes the current to flow.

Does current flow with voltage?

When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current. In a single (one loop) circuit, the amount of current at any point is the same as the amount of current at any other point.

Does current depend on voltage?

The force motivating charge carriers to “flow” in a circuit is called voltage. Voltage is a specific measure of potential energy that is always relative between two points. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow.

Does current depend on load?

The current drawn by the load would be equal to the current through the circuit, right?(assuming the load is connected in series). Using ohm’s law, the current through the circuit would hence be 2A. Edit: this highly upvotedsays that for a constant voltage supply, current drawn depends on load.

What causes a open circuit?

Any interruption in the circuit, such as an open switch, a break in the wiring, or a component such as a resistor that has changed its resistance to an extremely high value will cause current to cease. The open switch or the fault has caused what is commonly called an OPEN CIRCUIT.

Which is more dangerous open or short circuit?

The Short Circuit A short circuit has the potential to be far more dangerous and destructive than an open circuit. Using Ohm’s Law we know that a decrease in resistance will cause an increase in amperes.
