Let I current flowing through a resistor of resistance R and potential across the resistor is V. When charge Q moves against the potential difference V in time t, the amount of work is, workdone by battery for moving the charge in electric circuit (W) = Vit. While in series combination, equivalent resistance is always greater than any individual resistance. Potential difference between two points is the workdone per unit charge in taking the charge from one point to another. thankyou. We use electricity virtually every minute of every day for example in lighting, heating, refrigeration, air conditioning, power electromagnets, power computers , power televisions, power pumps, power our vehicles etc. The maximum value of electric current that can pass through an electric appliance without damaging electric appliance is called current rating of electric appliance. Heating Effect of Electric Current: When electric current is supplied to a purely resistive conductor, the energy of electric current is dissipated entirely in the form of heat and as a result, resistor gets heated. Resistance: Ratio of the applied voltage to the current flowing in the conductor is called resistance of the conductor. If a net electric charge (Q) flows through a cross-section of a conductor in time t, then, This heating of resistor is commonly known as Heating Effect of Electric Current. Thanks for learn this chapter unit of resistance is ohm. If we add potential difference across each one of resistors (R1, R2 and R3) then we get. THIS 1 volt is the potential difference between two points if 1 J of work has to be done in taking 1 C charge from one point to another. The +ve charge flows from higher to lower potential. In practical application, resistors are used to increase or decrease the electric current. More area of conductor facilitates the flow of electric current through more area and thus, decreases the resistance. Electric potential difference is known as voltage, which is equal to the amount of work done to move the unit charge between two points against static electric field. Combination of resistors (Series and Parallel combination), the heating effect of electric current and electric power. This heating effect is used in many appliances, such as electric iron, electric heater, electric geyser, etc. The revision notes help you revise the whole chapter in minutes. Resistivity: It is defined as the resistance offered by a cube of a material of side 1m when current flows perpendicular to its opposite faces. The resistivity of materials varies with temperature. We have more than 2000 questions (with answers) and several sample papers to help you prepare for Physics Class 10 Board exam. Expression of Electric Current: Electric current is denoted by the letter ‘I’. This means electric current will decrease with an increase in resistance and vice versa. I am heartily thanking you for providing such good notes. For exploiting the heating effect, the element of appliances must have high melting point to retain more heat. Ohm is denoted by Greek letter ‘Ω’. Positive and negative charges: The charge acquired by a glass rod when rubbed with silk is called positive charge and the charge acquired by an ebonite rod when rubbed with wool is called negative charge. Thus, work done in moving of charge (Q) of potential difference (V), Cause of Resistance in a Conductor: Flow of electrons in a conductor is electric current.
