How much current is drawn by a television with a resistance of 45 that is connected across a potential difference of 120 V?

Answer 1

To find the current drawn by the TV, you can apply Ohm's law:

V = I × R,

where V is voltage in Volts (V), I is current in Amperes (A), and R is resistance in Ohms (Ω).

So using the TV's resistance of 45 Ω and the applied potential difference of 120 V, we can:

1. Substitute into Ohm's Law, and
2. Solve for the current:

(120 V) = I × (45 Ω)

I = (120 V) / (45 Ω) = 2.67 A.

So the TV draws 2.67 amps when connected across a potential difference of 120 V.
