Question

A current of 5 A flows through a wire for 10 s. If the potential difference across the wire is 50 V, how much energy is gained by the total charge flowing through the wire in this time?

Answer 1

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 seconds…a watt is a joule/second, so over 10 seconds you have 150x10 joules built up.

Answer 2

Answer:

In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.
