10.3 Electrical energy and power

Card 1 of 23

What happens to the energy carried by charge as the charge passes through a resistive wire?

A

The charge continues through, but its energy is transferred to the metal lattice.

B
  • Heating makes the filament emit visible light.
  • Most energy leaves as unwanted infrared radiation.
C

No - dissipation occurs in the conductor, and insulation can trap energy.

D

The power becomes four times greater because P∝I2P\propto I^2P∝I2.
