Answer:
480 Ohms
Explanation:
Resistance: This can be defined as a opposition to current flow in an electric circuit. The S.I unit of resistance is ohms(Ω).
From the question,
V = IR................... Equation 1
Make R the subject of the equation
R = V/I............... Equation 2
V = The House voltage, I = Current, R = Resistance of the bulb.
Given: V = 240 Volts, I = 0.5 Amps.
Substitute into equation 2
R = 240/0.5
R = 480 Ohms
Hence the resistance of the bulb is 480 Ohms
