bridge power audio amplifier
Which amplifier provides twice output swing as that of LM380 amplifier? Explanation: In bridge power audio amplifier, two LM380s are used in bride configuration. Therefore, the maximum output voltage swing will be twice that of a single LM380 amplifier. 10.

Why do we need amplifier?
An electronic amplifier is a device that is used to increase the power, current, or voltage of a signal. Amplifiers are used in music equipment, electronic devices such as television and radio receivers, audio equipment, and computers to increase the amplitude of a signal.
Do transistors consume power?
Power dissipation At any given time, the power dissipated by a transistor is equal to the product of collector current and collector-emitter voltage. Just like resistors, transistors are rated for how many watts each can safely dissipate without sustaining damage.
Why do we need power transistor?
The power transistor is a transistor that used in high power amplifier and power supplies. Power transistors are suited for application where a lot of power is being used current and voltage. It is a junction transistor, is designed to handle high current and power and also used in audio and switching circuits.
What is the maximum voltage for transistor?
A typical value for a small signal transistor is 60 to 80 V. In power transistors, this could range to 1000 V, for example, a horizontal deflection transistor in a cathode ray tube display.
What is the main purpose of amplifier?
An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. They can be categorized as either weak-signal amplifiers or power amplifiers.
