So EMF is simply voltage or so called terminal voltage. When there is no current flowing through the battery, there is a max voltage. EMF causes generation of electrical energy from chemical energy. When the current begins flowing, the voltage drops across the resistor. So the E = W/q AND V=IR, so when we do circuit problems

The voltage across the circuits, when there is no current flowing through it is not zero

What is the significance of E, is it simply that it helps to generate electricity in a battery. I'm confused with the relation between E and V and why is this important, how does it relate to what we are doing in circuits
