Assertion: A capacitor blocks direct current in the steady state.
Reason : The capacitive reactance of the capacitor is inversely proportional to frequency
f of the source of emf.
Capacitive reactance
Frequency of direct current is zero i.e.
Thus resistance of capacitor for direct current is very large and so it do not allow the direct current to pass through it.
Hence, option A is correct.

When temperature of the conductor is increased, then the collision frequency between current carries ( electrons ) and atoms increases. This results in
wires (same length, same area, same material) are connected in parallel and each has resistance, then the equivalent resistance will be
A wire has resistance of . It is cut into two parts and both have are connected in parallel. The new resistance is?
The voltage - current graph of a metallic conductor at two different temperature and is shown below. At which temperature is the resistance higher?
