Formula

I = V / Rtotal

I = 6 / 10 = 0.60 A

Try this

Build a closed circuit that lights the bulb, then make the current visible by reducing resistance or increasing voltage.

The circuit is closed, but current is low. Reduce resistance or increase voltage.

You need a battery, bulb, switch, resistor, and a closed switch.

What happens in the circuit?

What happened?

The path is closed, so current flows and the bulb lights.

Why?

Current needs a complete path from and back to the battery. Increasing resistance reduces current.

Learning Objectives

  • A closed path is required for current.
  • A switch opens or closes a circuit.
  • More resistance reduces current.
