Answer:
The current through the resistor is 0.5 A
Explanation:
Given;
power of the light bulb = 60 W
voltage in the wall outlet across the plug terminals = 120 V
power of the light bulb is the product of voltage in the wall outlet across the plug terminals and the current passing through the resistor.
power = voltage x current
[tex]Current = \frac{power}{voltage} = \frac{60}{120} = 0.5 A[/tex]
Therefore, for a 60 W light bulb powered by a connection to a wall outlet with 120 V across the plug terminals, the current passing through the resistor is 0.5 A
Answer:
0.5 A
Explanation:
Current: The can be defined as the rate of flow of charge around a circuit. The S.I unit of current is Ampere(A)
Using,
P = VI..................... Equation 1
Where P = Power rating of the bulb, V = Voltage of the wall outlet, I = Current passing through the resistor.
Make I the subject of the equation
I = P/V................. Equation 2
Given: P = 60 W, V = 120 V.
Substitute into equation 2
I = 60/120
I = 0.5 A.
Hence the current passing through the resistor = 0.5 A
