Question

If household voltage is 120 volts, what is the resistance created by the light bulb with 0.5 amps of current flowing through it?

Answer 1

Answer:

R = 240 Ω

Explanation:

The resistance created by the light bulb can be calculated by using Ohm's Law:

$V = IR\\\\R =\frac{V}{I}$

where,

R = Resistance created by the light bulb = ?

V = Voltage across the bulb = 120 volts

I = current passing through the light bulb = 0.5 A

Therefore,

$R = \frac{120\ volts}{0.5\ A}$

R = 240 Ω
