Full-text (PDF) | In this paper some basic terms such as voltage and potential difference are presented. In many cases they are regarded as identical which leads to confusion with understanding of the fundamental concept of electromagnetic field. Related to this topic, some authors in their books
Emf is not a physical force. In simple words, it may be stated as electromotive force is the maximum voltage that can be attained by a specific circuit. Potential Difference. Potential difference is the work done per unit charge to move a charge between the negative and the positive terminal of the battery.
The EMF is the maximum voltage that the battery can deliver whereas the magnitude of the potential difference is always less than the maximum possible value of emf. The emf force gains the electrical energy in the circuit whereas the potential difference loss the electrical energy in the circuit.
Objectives: After completing this module, you should be able to: •• Solve problems involving emf, terminal potential difference, internal resistance, and load resistance. •• Solve problems involving power gains power gains and losses losses in a simple circuit containing internal and load resistances. •• Work problems
between two points when no current flows is equal and opposite to the electrostatic potential difference. This means that the electrostatic potential difference between the terminals of an open circuit source = - the e.m.f. between the terminals as measured within the con- ductors. There is an e.m.f.
vd is very small around 0.1 mm s-1. Clearly, the current is proportional to drift velocity. I ? vd. For many materials, including metals, vd ? E. So I ? E. Consider a section of a conductor with cross sectional area A and length L. Let a potential difference ?V be applied between the two ends, so. L. V. E. ?. = Current: I ? E and.
15 Aug 2011 EMF vs Voltage. Both voltage and EMF (electromotive force) describe the electrical potential difference, but are different terms. The term 'voltage' has a common use, and it is same as the electrical potential difference. But, EMF is a specific term and used to describe a voltage generated by a battery. Voltage.
The distinction between emf and potential difference is often glossed over and often misunderstood so this is an appropriate and interesting question. Since both emf and potential difference are measured in volts, it is quite easy to use the terms interchangeably and, in many cases, there's no harm done but
Ideal emf device maintains a constant potential difference between its terminals, independent of I. Electric force: Non electrostatic force: maintains potential difference between terminals. If F n="0" > charge will flow between terminals until V ab. =0 displacement opposite to. F e > potential energy. Increases by q·V ab.
