A student sets up a simple electric circuit with a 6 V battery and a lamp. When the switch is closed, a current of 0.5 A flows.
Using the idea of electric current, what does the value 0.5 A represent?
Using the idea of electric current, what does the value 0.5 A represent?
- 0.5 joule of energy is supplied to the lamp every second.
- 0.5 coulomb of charge passes a point in the circuit every second.
- 0.5 volt is used up by the lamp every second.
- 0.5 ohm is the resistance of the lamp.
