Question

If electromotive force of battery is 5 volt Total energy supplied by battery is

Answer 1

Explanation:

It depends...

To get energy consumed from the battery, you need two more variable to solve.

Eg:

V (Which is, = EMF, considering no internal resistance) = 5

Let's say, current drawn from this battery be 1A & for 1 min, then,

E = V.I.T

 =  5*1*60

 = 300J

Now, if you use the battery for an hour,

E =  5*1*60*60

  = 18000J = 18kJ

~ly, change the current drawn, energy will change...

Hope that explains...

Answer 2

The total energy supplied by the battery is 5 Joules.

• The electromotive force or EMF is the amount of energy supplied by a cell or a battery per coulomb of charge passing through it.
• EMF = E / Q,  where E is energy and Q is the charge per Coulomb
• But, EMF is the total amount of electrical energy which a battery can supply when it is not connected to an external circuit. As soon as we connect the battery to an external circuit, it undergoes loss because of the resistance of the circuit.

• Then the EMF becomes a potential difference PD.

Thus a battery with an Emf rating of 5V can supply a maximum of 5V of electrical energy in an open circuit.
