CBSE Class 10: Current and Voltage Videos | Power rating

• What happens to the force between two charges if the distance between them is
• what was a unit of current?
• Will a current carrying conductor produce an electric field?
• if one microampere current flows through a conductor for 10 seconds how many electrons will pass at the point of cross section
• In a household five tube lights of 40 volt each are used for 5 hours and electric press of 500 volt for 4 hours everyday. Calculate the total energy consumed by the tubelight and press in a month of 30 days
• what is volt
• why does need to maintain the current in a given electric circuit by expanding its energy stored in it?
• The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
• If charge on one electron is 1.6 x 10 ^-19 C. Calculate number of electrons required to constitute 1A of current in 1s.
• what is the power of torch bulb rated at 2.5V and 500 mA?
