Does the direction of EMF depend on direction of current?
Does the direction of EMF depend on direction of current? Direction of EMF is decided by the construction of the battery cell, it does not depend upon the direction of the current flow. In fact direction of the current flow depends upon the direction of emf. However direction of the voltage drop depends upon the […]
What happens to the electrons in the anode?
What happens to the electrons in the anode? In electrochemistry, the anode is where oxidation occurs and is the positive polarity contact in an electrolytic cell. At the anode, anions (negative ions) are forced by the electrical potential to react chemically and give off electrons (oxidation) which then flow up and into the driving circuit. […]
