ANSWER
0.75 Amps
EXPLANATION
Given:
• The power of the light bulb, P = 90 W
,• The voltage of the source, V = 120 V
Find:
• The current through the light bulb, I
The power of a device, P, is related to the voltage, V, and current, I, through the following equation,
[tex]P=V\cdot I[/tex]Solving for I,
[tex]I=\frac{P}{V}[/tex]Substitute the known values and solve,
[tex]I=\frac{90W}{120V}=\frac{3}{4}Amps=0.75Amps[/tex]Hence, the current through the light bulb is 0.75 Amps.
