Current & Voltage Course

Lesson 16 of 16: Voltage vs Current Comparison

Move step by step through the course and keep track of where you are.

Simulation

Watch voltage and current side by side

Use the live circuit to see the difference between the electrical push and the actual flow. Then compare how both values respond when the lesson numbers change.

Voltage

12.0 V

Current

2.00 A

Resistance

6.0 Ohm

Core idea

Voltage is the electrical pressure that pushes charge. Current is the actual flow of charge through the wire.

Simple idea: Voltage pushes -> Current moves
Comparison View

Watch the push and the flow together

Voltage tells us how hard the source is pushing. Current shows how much charge is actually moving through the same circuit.

Voltage

Level: MEDIUM

12.0 V

Voltage is the pushing force behind charge movement.

Current

Level: MEDIUM

2.00 A

Current is the actual amount of charge flowing in the wire.

Beginner Summary

Keep the comparison simple

If you remember what voltage does and what current shows, circuit reading becomes much easier.

Live
Voltage is the push that tries to move charge. Current is the amount of charge that is actually moving in the circuit.

Voltage

Voltage tells us how strongly the source is pushing electric charge.

Current

Current tells us how much charge is really moving through the wire.

Relationship

If resistance stays the same, more voltage usually creates more current.
