when a conductor carrying 2.5x10-3 C is discharged to earth, a current of 4mA is needed. How long does the discharge take?
The electric field between two parallel square metal plates is 130 N/C. The plates are 0.85 m on a side and are separated by 3.0 cm. What is the magnitude of the charge on each plate (each plate has equal charge and opposite sign)? Neglect edge effects.
Two cell each of e.m.f 1.5 volts and internal resistance of 1.5 ohms are connected In series.What is the currents in the resistor of 20 ohms connected across the end of the series combination
Three resistances of 4Ω, 8Ω 𝑎𝑛𝑑 16Ω are connected in a parallel to a 220 V supply. Calculate the equivalent resistance and current in circuit?
there are number of reasons why practical work is done. design a poster/flyer/leaflet to show/explain to the group of leaners why practical work is necessary.
