Two resistances 18 Ω and 6 Ω are connected to a 6 V battery in series.
Calculate
(a) the total resistance of the circuit,
(b) the current through the circuit
24 Ω and 0.25 A
10 Ω and 0.20 A
12 Ω and 1.30 A
30 Ω and 0.25 A
Consider the following statements:
Assertion (A) : In an electric bulb,the filament is in the form of a coiled coil
Reason (R ): A coiled coil filament occupies less space and id therefore,not cooled significantly by the convection current in the bulb.
Both A and R are true, but R is the correct explanation of A
Both A and R are true, but R is not the correct explanation of A
A is true, but R is false
A is false but R is true
Consider the following statements:
Assertion (A) : Electric power is transmitted over long distances through conducting wires of very high voltages
Reason (R ): Then only the power can be supplied to the individual houses
Both A and R are true, but R is not the correct explanation of A
Both A and R are true and R is the correct explanation of A
Both A and R are false
A is false but R is true
