Question

potential difference across the battery terminals is 100 volts . if 25joule of energy is transferred ino.25 second. calculate the electric current flows​

Answer 1

Answer:

Potential diff ( v ) = 100 volts

Energy = 25 joule

Time ( t ) = 25 seconds

Current ( I ) = ?

According to Energy Formula

Energy = Power * Time

25 = Power * 25

25 / 25 = Power

1 = power

Now,

According to Power Formula

Power = Potential diff * Current

1 = 100 * Current

1 / 100 = Current

00.1 ampere = Current

:. Current ( I ) = 00.1 ampere
