How do you calculate voltage drop in a series circuit? To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm’s Law is E=I⋅R , which tells us to then multiply I by R . E is the voltage across the component also […]
What can the speaker do to help the audience better receive the message?
What can the speaker do to help the audience better receive the message? Key Points The speaker can direct the attention of the audience to what is important by using changes in rate and volume, body movement, and gesture to emphasize what is important. It is important to read the non-verbal clues of the audience […]
What is the efficiency at maximum power transfer condition?
What is the efficiency at maximum power transfer condition? The efficiency is only 50% when maximum power transfer is achieved, but approaches 100% as the load resistance approaches infinity, though the total power level tends towards zero. Efficiency also approaches 100% if the source resistance approaches zero, and 0% if the load resistance approaches zero. […]
What is a bimetallic strip made of?
What is a bimetallic strip made of? The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass. How does a bimetallic strip work? Bimetallic strips A traditional thermostat has two pieces of different metals bolted together […]

Which of the following is an essential safety procedure that protects workers from injury while working on or near electrical circuits and equipment? Lock-out/tag-out What are the most common electrical safety issues that safety professionals encounter? The following hazards are the most frequent causes of electrical injuries: contact with power lines, lack of ground-fault protection, […]
Why is RAM faster than rom?
What factors influence the final properties of composites?
What factors influence the final properties of composites? The reconfiguration of the composite structure depends on many parameters, such as the material properties, lay up sequence, fiber orientation, thickness, and the strategic position of laminae with different orientations. What do the properties of composite materials depend upon? The mechanical properties of composite materials usually depend […]
Which materials are good conductors and which are good insulators?
Which materials are good conductors and which are good insulators? Wool, dry air, plastics, and polystyrene foam are all examples of good insulators. Materials that do not insulate well are called conductors. Conductors have loose bonds that allow particles to move easily and transfer energy from one particle to the next. Metals tend to be […]
