The filament resistance when a 6 volt bulb draws a current of 0.5 Amps is 12 ohms.
Given:
Voltage = 6 Volts
Current = 0.5 Amp
To find:
Resistance
Solution:
We know from the properties of Ohm's Law that if I amp is the current passing through a substance over a voltage of V volts , then the resistance of the substance is given by :
R = V / I
Here we will use the given values to calculate the resistance of the bulb.
R = 6 /0.5
or, R = 12 Ω (Ω represents ohm which is the unit of resistance)
Therefore the filament resistance of the bulb is 12 ohm.
