Bad conductor are also known as insulators. The S.I. Since, the electric energy is supplied for time ?, thus, after multiplying both sides of equation (ii) by time t, we get, i really love this site. I am heartily thanking you for providing such good notes. This heating effect is used in many appliances, such as electric iron, electric heater, electric geyser, etc. If we add potential difference across each one of resistors (R1, R2 and R3) then we get. Please post your doubts in doubts.dronstudy.com Our faculty will reach you out there. (i) Unlike charges attract each other and like charges repel each other. Unit of Electric Potential Difference (Voltage) Each matter contains some protons, electrons and neutrons. Electric Current: The amount of flow charge through any cross-sectional area of a conductor in unity time is called Electric Current. Ampere is the flow of electric charge through a surface at the rate of one coulomb per second. CBSE Notes - NCERT Solutions. But in parallel connection, different devices need different current for proper working. 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. Electric current can be defined as the flow of charge from one point to another. Chemical energy of battery is converted to heat energy in the resistor. (i) Positive charge. Itotal = 6A + 48A + 30A + 12A + 24A = 120A. Thanks for learn this chapter The difference of electric potential between any two points in the electric field is called Electric Potential difference. R = \(\frac { V }{ I }\) Electric potential: Electric Potential at any point in the electric field is defined as the amount of work done to bring the unit positive charge from infinity (from outside the electric field) to that point. Resistance: Ratio of the applied voltage to the current flowing in the conductor is called resistance of the conductor. Notes for electricity chapter of class 10 science. var m = now.getMinutes(); 1. Where is electric fuse , short circuit. Resistivity, ρ = \(\frac { RA }{ l }\) I = \(\frac { Q }{ T }\). Set up a circuit as shown above. It helps me at last moment!

Very easy and so much useful notes that is really good. => Resistance of device = (Voltage rating)2 / Power rating. really helpful at the end moment to revise the whole content. Cause of Resistance in a Conductor: Flow of electrons in a conductor is electric current. So keep it up. Such materials are called bad conductors. The potential difference through the resistor is = V. If positive charge flows, direction of electric current is same as direction of flow of charge. Expression of Electric Current: Electric current is denoted by the letter ‘I’. how resistance increase with temperature. This means R will decrease with increase in the area of conductor and vice versa. The -ve charge flows from lower to a higher potential. The expression for the electric current can be written as: I = q / t. Model of Electron Sea or P = \(\frac { W }{ t }\) (ii) Parallel combination. Therefore, Voltage = \(\frac { Workdone }{ Charge }\) With the help of Notes, candidates can plan their Strategy for particular weaker section of subject and study hard. S.I.
