begins with the specification‚ which states the functionality that the finished design must provide‚ but does not indicate how it is to be achieved. The initial specification for this project is a dc voltmeter with an input voltage range of 0 to 300 volts. Although there are many parameters that a design specification should contain‚ such as size‚ weight‚ moisture resistance‚ temperature range‚ thermal output‚ vibration tolerance and acceleration tolerance but we shall only pursue electronic circuit

of gas in the air decreases to a safe level. The circuit uses an MQ6 gas sensor‚ which is designed to sense LPG‚ propane and isobutene gases. Circuit and working Fig. 1 shows the circuit of the LPG sensor. The circuit is built around 5V volt age regulator 7805 (IC1)‚ gas sensor MQ6 (GS1)‚ counter IC 4060 (IC2) and a few discrete components. GS1 is a six-pin gas sensor that can detect very small traces of LPG in the air and has a swift response time. However‚ it Has very less sensitivity

Why is it important to remove loose jewelry before working inside a computer case? Jewelry might fall into and/or get caught on any of the components of the machine and corrupt or damage it including potential for static electricity as low as 10 volts. 3. When assembling a system‚ which do you install first‚ the drives or the motherboard? Motherboard 4. What is the purpose of raised screw holes or stadoffs installed between the motherboard and the case? If the bottom of the motherboard touches

This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced emf in volt and ψ is the flux linkages in Weber turn. Fig. 1 shows a Figure 1: Flux linkages of a coil coil of N turns. All these N turns link flux lines of φ Weber resulting in the Nφ flux linkages. In such a case‚ ψ = Nφ and e=N dφ dt volt (3) (2) The change in the flux linkage can be brought about in a variety of ways • coil may be static and unmoving but the flux linking

Background EMF (electromotive force) is a measure of work done per unit of charge and is measured in volts. Internal resistance is resistance in ohms of the cell. I will be using a 1.5V battery in the experiment. I will measure the voltage and current using multimeters. Calculation method I intend to rearrange the equation ‘ε=Ir+IR’ to form ‘V= -Ir +ε’
