What are the differences between the circuits you find in your house and

the circuits on a microchip in a computer?

Check explanations below

Explanation:

The circuits in the house uses an alternating voltage, For example the United States uses 120V 60 Hz AC. The circuits in the house use electrical components that are large such as switches, Contactors and circuit breakers, distribution board, Gear switches, lampholders, etc.  

The circuits on a microchip in a computer uses a direct current supply. The voltage requirement is usually low (between 5V and 12V). In addition, micro electronic components, such transistors, resistors, low resistance wires, capacitors (in microFarad) are used.  

Typically, the Home circuit is an electrical circuit while the circuit on the computer microchip is an electronic circuit with low voltage and current requirement and low power consumption.

answer; ///(74) degrees is your answer..

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
