On successful completion of the course students will be able to:ġ. To find out which courses are recommended for Bachelor programs, please see: Availability 2022 Course Timetables Students who intend to study engineering and meet the assumed knowledge for EPPHYS152 and EPPHYS252 should enrol in EPPHYS152 and EPPHYS252 instead of EPENGG101.
#TUTORIAL 6 PHYSICS 101 PROFESSIONAL#
These activities will further their understanding of the engineering problem solving cycle and the professional and technical skills engineers require. Students will participate in a range of learning activities including tutorials, laboratories, and a group project. The course will develop practical problem solving, report writing, oral presentation skills and teamwork, as essential skills for future undergraduate study. The focus of the course is on integrating critical thinking with an introduction to physics and physics problem solving. The SI unit of electric power is watt ( W).EPENGG101 introduces students to the problem solving skills that are integral to an engineering workplace.
The rate at which electric energy is dissipated or consumed in an electric circuit is known as electric power. The following table describes some of the symbols commonly used to define the electric components −Ī German physicist, Georg Simon Ohm in 1827, stated that “The electric current flowing through a metallic wire is directly proportional to the potential difference (V), across its ends provided its temperature remains the same.” Some defined symbols are used to illustrate the most commonly used electrical components in circuit diagrams. The instrument that measures the potential difference is known as the voltmeter. Further, when this cell is linked to a conducting circuit element, the potential difference sets the charges in motion (in the conductor) and generates an electric current.Īlessandro Volta (1745–1827), an Italian physicist, first noticed the electric potential difference therefore, the SI unit of electric potential difference is given volt ( V). The chemical action within a cell produces the potential difference across the terminals of the cell. The electrons of a conductor move only if there is a difference of electric pressure, known as the potential difference. The electric current flows in the circuit starting from the positive terminal to the negative terminal of the cell through the bulb and ammeter.Įlectric Potential and Potential Difference The instrument that measures electric current in a circuit is known as ammeter. One ampere constitutes by the flow of one coulomb of charge per second, i.e., 1 A = 1 C/1 s. It was named after the French scientist Andre-Marie Ampere. The electric current is expressed by a unit known as an ampere ( A). The SI unit of electric charge is coulomb ( C).Ĭoulomb is equivalent to the charge contained in closely 6 × 10 18 electrons. In an electric circuit, usually, the direction of electric current (known as positive charges), is considered as opposite to the direction of the flow of electrons, which are considered as negative charges. If the electric charge flows through a conductor, such as a metallic wire, it is known as the electric current in the conductor.Ī continuous and closed path of an electric current is known as an electric circuit (as shown in the image given below) −
