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.
