Why we use transistor instead of diode?
Diode is passive device where as Transistor is active device. Diode are of limited application, as there is no control between two terminals. In diode switching is achieved by changing direction of current, it act as uni-directional device.5 Feb 2016

Why is in-circuit testing important?
The purpose of in-circuit testing, or ICT, is to detect any defective components in a printed circuit board. During ICT, essential parameters such as resistance and capacitance are measured, along with the operations of various analog components and digital circuits.15 Nov 2021

Why is silicon called as semiconductor?
Electricity does not conduct in this pure monocrystalline silicon, when silicon is doped with impurities it becomes conductive. But silicon does not have conductivity comparable to conductors, it is very less but much more than that of insulators which is why it is called a semiconductor.

How to test a capacitor?
Connect the test leads to the capacitor terminals. Keep test leads connected for a few seconds to allow the multimeter to automatically select the proper range. Read the measurement displayed. If the capacitance value is within the measurement range, the multimeter will display the capacitor’s value.

What does N and P mean In semiconductor?
P-type semiconductors is positive type semiconductor it means it deficiency of 1 electron is required. N-type semiconductor is negative type semi-conductor it means excess of 1 electron is required. 4. In P-type semiconductor majority charge carries are holes and minority charge carries are electrons.

What are holes In semiconductor?
A hole is an absence of an electron in a particular place in an atom. Although it is not a physical particle in the same sense as an electron, a hole can be passed from atom to atom in a semiconductor material. Electrons and holes, both, are the charge carriers in any semiconductor substance.

How do you test a short circuit test?
Method. The test is conducted on the high-voltage (HV) side of the transformer where the low-voltage (LV) side (or the secondary) is short-circuited. A wattmeter is connected to the primary side. An ammeter is connected in series with the primary winding.

How are semiconductor wafers measured?
During the processing of semiconductor wafers, bow and warp are introduced to the wafer profile. Hence, to obtain a true thickness measurement a probe can be placed on either side of the wafer to prevent these surface irregularities from affecting the thickness calculation.23 Jan 2014
