Q1:- The SI unit of conductivity is
Q2:- A piece of oil soaked paper has been inserted between the plates of a parallel plate capacitor. Then the potential difference between the plates will
Q3:- The current drawn by a tungsten filament lamp is measured by an ammeter. the ammeter reading under steady state condition will be ------- the ammeter reading when the supply is switched on.
< hr="" />
Q4:- Four resistance 2 ,4, 5, 20 , ohm are connected in parallel. their combined resistance is
Q5:- The 200 W , 200 V bulb and a 100 W, 200 V bulb are connected in series and the voltage of 400 V is applied across the series connected bubs, under this conditions.
- ohm-m
- ohm/ m
- mho- m
- mho/m
Q2:- A piece of oil soaked paper has been inserted between the plates of a parallel plate capacitor. Then the potential difference between the plates will
- increase
- decrease
- remain unaltered
- become zero
Q3:- The current drawn by a tungsten filament lamp is measured by an ammeter. the ammeter reading under steady state condition will be ------- the ammeter reading when the supply is switched on.
- same as
- less than
- greater than
- double

Q4:- Four resistance 2 ,4, 5, 20 , ohm are connected in parallel. their combined resistance is
- 1 ohm
- 2 ohm
- 4 ohm
- 5 ohm
Q5:- The 200 W , 200 V bulb and a 100 W, 200 V bulb are connected in series and the voltage of 400 V is applied across the series connected bubs, under this conditions.
- 100 W bulb will be brighter than 200 w bulb
- 200 W bulb will be brighter than 100 W bulb
- both the bulb will have equal brightness
- both the bulbs will be darker than when they are connected across rated voltage
series parallel haha
