The current which does not change its direction is called:
Sound waves having frequency lower than 20 Hz are called:
If one of the resistors in a parallel circuit is removed,
the total resistance will be:
What happens to the intensity or the brightness of the lamps
connected in series as more and more lamps are added:
The waves which travel in straight line through space and
have strong signals are called:
If we double both the current and the voltage in a circuit
while keeping its resistance constant, the power:
