Question

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?

Answer 1

By using the Ohms law, we can calculate the current.

Ohms law,

`(V)/(I)  = R`

Here, V is potential difference, and R is the resistance.

Given,
`V=120 V` and
`R = 30 ohm`.

Therefore, putting the given values in above relation , we get

`(120V)/(I) = 30 ohm`

or
`I=(120)/(30) = 4 A`

Thus, the current is drawn by a television 4 Ampere
