Uses of Transistor:
In a transistor the base current it plays a significant role in the collector current IC. A small change in the base current forms a large change in the collector current. Because of this characteristic a transistor can also be used as an amplifier in more electronic devices.
Q. Helpful Henry's car is pushing Flat-tire Fred's car to the car shop. While the cars are accelerating up to 15 miles/hour Helpful Henry needs to push Fred's car with 60 N of for
An alternating voltage given by v=100sin240t volts is applied across a coil of resistance 32 and inductance 100mH. Verify (a) the circuit impedance, (b) the current flowing,
Illustrated below are 5 of the normal modes of ethylene (HCCH). At its equilibrium geometry this molecule has no dipole moment, but for some of the normal modes the distortion dur
