The formula which is describing above of emf is absolutely wrong, the correct one is Emf =V+ir.

Thanks all for explaining.

Emf unit is V and jouls per coulomb not Newton.

V= IR.
V=20*500.
V=10000.
V=20*500.
V=10000.

Here,
emf, refers to voltage generated by a battery.
So,
emf = v = I*R = 20*500 = 10,000V.
emf, refers to voltage generated by a battery.
So,
emf = v = I*R = 20*500 = 10,000V.

Yes chandu is correct because electro motive force refers to voltage generated by a battery or magnetic force according to faradays law.
So emf=I*R.
So emf=I*R.

V = IR
V = 20*500 = 10,000 V.
V = 20*500 = 10,000 V.
