What are the limitations of Ohms Law?
what is resistivity ? and what is resistance ? differentiate between the two..
Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
(ii) parallel across the same voltage supply.
deduce ohms law by the concept of drift velocity
state ohms law and write the condition in which law is beyed?
why does temperature remain constant in ohm law
Whay is electrolysis? explain with some diagrams
Even though the drift speed of electron is only 1millimeter per second , why will any electronic appliance start as soon as we switch it on ?(if the drift speed of electron is 1mm per second it should take a long time for the appliance to get started )
A copper wire has diameter 00.5mm and resistivity of 1,6x10.8m. What will be the length of this wire to make its resistance 10 ohm. How does the resistance change if the diameter is doubled.
the rating of an electric heater is 1100W ,220V .calculate resistance when it operates at 220V. also calculate the energy consumed in KWH in the month of november of the heater, if used daily for four hours at the rated voltage
WHY IS ELECTRIC CURRENT A SCALAR QUANTITY?
a voltmeter has aleast count of 0.05 volt.while doing Ohm 's law experiment,a student observed that the pointer of the voltmeter coincides with 15th division.the observed reading is :
(a) 0.75 v
(b) 0.075 v
(c) 7.5
(d) 75
masses of three wires of copper are in the rati of 1:3:5 and their length are in the ratio of 5:3:1.The ratio of their electric resistence is
