Q1.A current of 10A flows through a wire for 10s. If the potential difference of the wire is 15V, what will be the work done? ​

Answer 1

$\huge\underline\bold{\underline{♡Answer♡}}$

Step-by-step explanation:

It’s easiest to use watt-hours. The number of watts over 1 hour.

10 amps times 15 volts is 150 watts. the 10 seconds is 10/3600 of an hour. So 150*10/3600 is the result. watts x hours. 0.417 watt-hours.

If you want joules in a period of 10 second.A watt is a joule/second, so over 10 seconds you have 150x10 joules built up. 1500 joules.

Byeee!. :)
