Answer:
The high-beam filament has more resistance than low beam filament.
Explanation:
To determine if the 50 W dissipated by a car’s headlights on high beam, has more or less resistance, formula for power dissipated in the filament is used.
Power = IV
Voltage =IR
∴ Power = I*IR = I²R
where;
I is the current
V is the voltage
R is the resistance
From the equation above, Power dissipated is directly proportional to Resistance.
Hence, the high-beam filament has more resistance than low beam filament.
