Name a current which flows only in one direction and can also be obtained from a battery.
Alternating current
Direct current
Directional current
Both (b) and (c)
Direct current is the one which flows only in one direction and we get this from batteries.
The current which flows only in one direction and which we get from a battery is:
(a) What do you understand by the terms 'direct current' and 'alternating current' ?
(b) Name some sources of direct current and some of alternating current.
(c) Stated an important advantage of alternating current over direct current.
(d) What is the frequency of A.C. supply in India ?
Question 8 Choose the incorrect statement: (a) Fleming’s right-hand rule is a simple rule to know the direction of induced current (b) The right-hand thumb rule is used to find the direction of magnetic fields due to current carrying conductors (c) The difference between the direct and alternating currents is that the direct current always flows in one direction, whereas the alternating current reverses its direction periodically (d) In India, the AC changes direction after every 1/ 50 second
