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 […]
How do we get the impulse response function H T of a system given a system equation?
How do we get the impulse response function H T of a system given a system equation? Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system. If the system is linear and time-invariant (terms we’ll define later), then you can use the impulse response to […]
How do you calculate voltage drop in a series circuit?
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. […]
Is it better to wire solar panels in series or parallel?
Is it better to wire solar panels in series or parallel? The main thing to remember is that wiring in series will increase your voltage, while wiring in parallel will increase your amperage. Both of the voltage and amperage need to be considered when designing your system, especially when it comes to finding an inverter […]
How do you find the impulse response of an LTI system?
What element is a semiconductor?
