How much current is drawn by a television with a resistance of 21 that is connected across a potential difference of 120 V?
5.45A wasn't right
what the units of resistance? ohms? Kohms?
if ohms, current=120/21=5.71amps
To determine the current drawn by the television, you can use Ohm's Law, which states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by the resistance (R).
The formula is: I = V / R
In this case, the resistance (R) of the television is given as 21 Ω (ohms), and the potential difference (V) across the television is 120 volts.
Now, we can substitute these values into the formula:
I = 120 V / 21 Ω
Using a calculator, we can divide 120 volts by 21 ohms:
I ≈ 5.71 A
Therefore, the current drawn by the television is approximately 5.71 Amperes (A).
