What will happen if two electric bulbs of 25W and 100W? Answer : No,25 W` bulb will fuse. From this , it is clear that voltage across the 100W bulb (=88V) is lesser than specified (220V), while across the 25Wbb̲(=352V) is greater than specified (220V), so the 25W bulb will fuse. Which bulb will glow […]

How can we protect cliffs from erosion? Sea walls. Concrete walls that are placed at the foot of a cliff to prevent erosion. They are curved to reflect the energy back into the sea. How can we protect our coastal areas? 15 Ways to Help Protect the Ocean and Coasts, Regardless of Where You Live […]

How do you maximize generator output? Locate the throttle. This is usually on the side of a generator that does not have a voltage dial or at the top of one that does. It usually has “RPM” imprinted on it. By increasing the rpm, you will increase the power output. What is 50% load on […]

What is the unit of internal energy? joule What happens when internal energy increases? The internal energy is the total amount of kinetic energy and potential energy of all the particles in the system. When energy is given to raise the temperature , particles speed up and they gain kinetic energy. What do you mean […]

Why are digital signals more reliable? Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Sound signals can vary smoothly in volume […]

What happens to current in reverse bias? Reverse bias usually refers to how a diode is used in a circuit. If a diode is reverse biased, the voltage at the cathode is higher than that at the anode. Therefore, no current will flow until the electric field is so high that the diode breaks down. […]
