Glory All Formula Of Current
The ratio considers the weight of total current assets versus total current liabilities.
All formula of current. All terms E I R apply to the same two points in the circuit to that same resistor so we can use the Ohms Law formula with no reservation. These list of formula booklet physics of class 12 chapter Current Electricity. Our teachers have designed these concept notes for the benefit of Grade 12 students.
I E is the emitter current. No current can flow if the circuit is broken - for example when a switch is open. I B is the base current.
Therefore we can apply Ohms Law I ER to the current through the resistor because we know the voltage E across the resistor and the resistance R of that resistor. These seven quantities are called the seven dimensions of the physical world. All physical quantities can be expressed in terms of seven fundamental base quantities such as mass length time temperature electric current luminous intensity and amount of substance.
Less the current less heat produced. 1 ampere 625 108 electrons sec In metallic conductors the current is due to the motion electrons whereas in electrolytes and ionized gases both electrons and positive ions move in opposite direction. This is known as Joules law of heating.
The law implies that the heat produced in a resistor is directly proportional to the square of current for a given resistance It means if we double the currentthe heat becomes 4 times if we half the currentthe heat becomes 14 times Hencemore the currentmore the heat. Electric current is the rate of flow of electric charge. In common base configuration BJT is used as voltage gain amplifier where the gain A V is the ratio of output voltage.
What is the dimension formula of current. All Revision notes for Class 12 Physics have been designed as per the latest syllabus and updated chapters given in your textbook for Physics in Standard 12. Determine the magnitude of the current flowing through it.
