A typical color television draws about 2.8 A when connected to a 145 V source.
What is the effective resistance of the T.V. set?
Answer in units of Ω.
32.59
To find the effective resistance of the TV set, we can use Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) across the circuit divided by the resistance (R) of the circuit. Mathematically, it can be represented as:
I = V / R
In this case, the current (I) is given as 2.8 A, and the voltage (V) is given as 145 V. We need to solve for the resistance (R).
To do this, we rearrange the equation to solve for resistance (R):
R = V / I
Now we can plug in the given values:
R = 145 V / 2.8 A
Calculating the result:
R ≈ 51.79 Ω
Therefore, the effective resistance of the TV set is approximately 51.79 Ω.
