Explain the dilations of R and V in the picture. => R increased by 5 times, V reduced by 5 times or R dilated by scale factor 5, V dilated by scale factor 1 2 , center of dilation (0, 0) or R dilated by scale factor 1 2 , V dilat..

Numerical 03 - A transistor is connected in common emitter configuration. The collector supply is 8 V and the voltage drop across a resistor of 800 W in the collector circuit is 0.5 V. If the current gain factor ( a ) is 0.96, calculate the base curre..

A transistor is connected in common emitter configuration. The collector supply is 8 V and the voltage drop across a resistor of 800 W in the collector circuit is 0.5 V. If the current gain factor ( a ) is 0.96, calculate the base curre..

Two identical cells of EMF 1.5 V each joined in parallel provide supply to an external circuit consisting of two resistors of 17 W each joined in parallel. A very high resistance voltmeter reads the terminal voltage of the cell to be 1.4 V. What is the internal resis..

Voltage: 1.25V to 1.5 V It does not have a long life because the acidic NH 4 Cl corrodes the Zinc container. fig 5.14 - The Dry ce..

This is a portable form of Leclanche Cell. A moist paste of NH 4 Cl and ZnCl 2 is contained in a zinc vessel acting as the negative electrode. ZnCl 2 is added to the electrolyte NH 4 Cl. It keeps the paste moist because it is highly hygroscopic. The top is sealed with shellac or pitch so that paste..

Take a nichrome wire of about 50 cm length and apply a potential difference of 1.5 V from a battery. Measure the current flowing through the wire using an ammeter connected to it in series, and note the potential difference across the resistance using a voltmeter connected acro..

(i) When A = 0, the base of transistor also get earthed. Now emitter base function is not forward biased but base-collector function is reverse biased. As the emitter current is zero, the base current is also zero and hence the collector current will also be zero. Hence the output Y is 1 (..

Source of Electricity - Electrons in different metals can have different energies. If two of these metals are placed in a conducting liquid (electrolyte) a difference in electrical potential is set up between them. A pair of different metals arranged in this way is an electrochemical cell. It conve..
