Question

a current of 5 ampere flows through an electric press of resistance 44 ampere calculate the energy consumed by the press in 5 minutes​

Answer 1

Answer:

330 kJ

Explanation:

According to the given question,

I = Current = 5 A

R = Resistance = 44 ohm

t = time = 5 min = 5×60 = 300 sec

And we are asked to calculate the energy consumed by the press.

An electric press works on heat energy principal and this heat energy is because of resistance and electric current in the press for some time.

We know,

• H = I^2 × R × t

Where, H = energy consumed by the press which then gets converted into heat energy.

Putting the values we get,

• H = 25 × 44 × 300

• H = 330,000 J

• H = 330 kJ

Thus energy consumed by the press when current flowing through it after 5 min is 5 A with resistance of 44 ohm is 330 kJ respectively.
